Linus Torvalds 09ca8dc7d6 Merge tag 'f2fs-for-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs 
Pull f2fs updates from Jaegeuk Kim:
 "The changes primarily focus on filesystem error reporting, reducing
  memory footprint by reverting in-memory data structures used for
  runtime validation, honoring FDP hints, and adding trace and debug
  logs. In addition, there are critical bug fixes resolving
  out-of-bounds read vulnerabilities in inline directory and ACL
  handling, potential deadlocks in balance_fs, use-after-free issues in
  atomic writes, and false data/node type assignments in large sections.

  Enhancements:
   - Revert  in-memory sit version and block bitmaps
   - support to report fserror
   - add trace_f2fs_fault_report
   - add iostat latency tracking for direct IO
   - add logs in f2fs_disable_checkpoint()
   - honor per-I/O write streams for direct writes
   - map data writes to FDP streams
   - skip inode folio lookup for cached overwrite
   - skip direct I/O iostat context when disabled
   - revert "check in-memory block bitmap"
   - revert "check in-memory sit version bitmap"

  Fixes:
   - optimize representative type determination in GC
   - fix incorrect FI_NO_EXTENT handling in __destroy_extent_node()
   - fix potential deadlock in f2fs_balance_fs()
   - fix potential deadlock in gc_merge path of f2fs_balance_fs()
   - atomic: fix UAF issue on f2fs_inode_info.atomic_inode
   - fix missing read bio submission on large folio error
   - pass correct iostat type for single node writes
   - fix to do sanity check on f2fs_get_node_folio_ra()
   - validate orphan inode entry count
   - keep atomic write retry from zeroing original data
   - read COW data with the original inode during atomic write
   - validate inline dentry name lengths before conversion
   - validate dentry name length before lookup compares it
   - reject setattr size changes on large folio files
   - revert "remove non-uptodate folio from the page cache in move_data_block"
   - validate ACL entry sizes in f2fs_acl_from_disk()
   - bound i_inline_xattr_size for non-inline-xattr inodes
   - fix listxattr handling of corrupted xattr entries
   - fix to round down start offset of fallocate for pin file"

Linus Torvalds a552c81ff4 Merge tag 'mm-stable-2026-06-18-09-26' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 
Pull MM updates from Andrew Morton:

 - "selftests/mm: clean up build output and verbosity" (Li Wang)

   Remove some noise from the MM selftests build

 - "mm: Free contiguous order-0 pages efficiently" (Ryan Roberts)

   Speed up the freeing of a batch of 0-order pages by first scanning
   them for coalescing opportunities. This is applicable to vfree() and
   to the releasing of frozen pages

 - "mm/damon: introduce DAMOS failed region quota charge ratio"
   (SeongJae Park)

   Address a DAMOS usability issue: The DAMOS quota often exhausts
   prematurely because it charges for all memory attempted, causing slow
   and inconsistent performance when actions fail on unreclaimable
   memory.

   To fix this, a new feature lets users set a smaller, flexible quota
   charge ratio (via a numerator and denominator) for failed regions.
   Since failed actions cause less overhead, reducing their quota cost
   ensures more predictable and efficient DAMOS processing

 - "selftests/cgroup: improve zswap tests robustness and support large
   page sizes" (Li Wang)

   Fix various spurious failures and improves the overall robustness of
   the cgroup zswap selftests

 - "fix MAP_DROPPABLE not supported errno" (Anthony Yznaga)

   Fix an issue in the mlock selftests on arm32

 - "mm: huge_memory: clean up defrag sysfs with shared" (Breno Leitao)

 - "treewide: fixup gfp_t printks" (Brendan Jackman)

   Use the special vprintf() gfp_t conversion in various places

 - "mm: Fix vmemmap optimization accounting and initialization" (Muchun
   Song)

   Fix several bugs in the vmemmap optimization, mainly around incorrect
   page accounting and memmap initialization in the DAX and memory
   hotplug paths. It also fixes pageblock migratetype initialization and
   struct page initialization for ZONE_DEVICE compound pages

 - "mm/damon: repost non-hotfix reviewed patches in damon/next tree"

   A sprinkle of unrelated minor bugfixes for DAMON

 - "mm: remove page_mapped()" (David Hildenbrand)

   Remove this function from the tree, replacing it with folio_mapped()

 - "mm/damon: let DAMON be paused and resumed" (SeongJae Park)

   Allow DAMON to be paused and resumed without losing its current state

 - "kasan: hw_tags: Disable tagging for stack and page-tables" (Muhammad
   Usama Anjum)

   Simplify and speed up kasan by removing its ineffective tagging of
   stacks and page tables

 - "mm/damon/reclaim,lru_sort: monitor all system rams by default"
   (SeongJae Park)

   Simplify deployment on diverse hardware like NUMA systems by updating
   DAMON_RECLAIM and DAMON_LRU_SORT to automatically monitor the
   physical address range covering all System RAM areas by default,
   replacing the overly restrictive behavior that only targeted the
   single largest memory block to save on negligible overhead

 - "mm/damon/sysfs: document filters/ directory as deprecated" (SeongJae
   Park)

   Update some DAMON docs

 - "mm: use spinlock guards for zone lock" (Dmitry Ilvokhin)

   Switch zone->lock handling over to using the guard() mechanisms

 - "mm/filemap: tighten mmap_miss hit accounting" (fujunjie)

   Fix a flaw where the mmap_miss counter over-credited page cache hits
   during fault-arounds and page-fault retries. This results in
   significant reduction of redundant synchronous mmap readahead I/O,
   drastically cutting down execution time and gigabytes read for sparse
   random or strided memory access workloads

 - "selftests/cgroup: Fix false positive failures in test_percpu_basic"
   (Li Wang)

   Fix a couple of false-positives in the cgroup kmem selftests

 - "mm/damon/reclaim: support monitoring intervals auto-tuning"
   (SeongJae Park)

   Add a new parameter to DAMON permitting DAMON_RECLAIM to
   automatically tune DAMON's sampling and aggregation intervals

 - "mm/damon/stat: add kdamond_pid parameter" (SeongJae Park)

   Change DAMON_STAT to provide the pid of its kdamond

 - "mm/kmemleak: dedupe verbose scan output" (Breno Leitao)

   Remove large amounts of duplicated backtraces from the verbose-mode
   kmemleak output

 - "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)" (David
   Hildenbrand)

   Reduce our use of CONFIG_HAVE_BOOTMEM_INFO_NODE, with a view to
   removing it entirely in a later series

 - "mm/damon: validate min_region_size to be power of 2" (Liew Rui Yan)

   Prevent users from passing a non-power-of-2 value of `addr_unit', as
   this later results in undesirable behavior

 - "mm: document read_pages and simplify usage" (Frederick Mayle)

 - "tools/mm/page-types: Fix misc bugs" (Ye Liu)

   Fix three issues in tools/mm/page-types.c

 - "mm: misc cleanups from __GFP_UNMAPPED series" (Brendan Jackman)

   Implement several cleanups in the page allocator and related code

 - "mm, swap: swap table phase IV: unify allocation" (Kairui Song)

   Unify the allocation and charging of anon and shmem swap in folios,
   provides better synchronization, consolidates the metadata
   management, hence dropping the static array and map, and improves
   performance

 - "mm/damon: introduce data attributes monitoring" (SeongJae Park(

   Extend DAMON to monitor general data attributes other than accesses

 - "mm/vmalloc: free unused pages on vrealloc() shrink" (Shivam Kalra)

   Implement the TODO in vrealloc() to unmap and free unused pages when
   shrinking across a page boundary

 - "mm/damon: documentation and comment fixes" (niecheng)

 - "remove mmap_action success, error hooks" (Lorenzo Stoakes)

   Eliminate custom hooks from mmap_action by removing the problematic
   success_hook which allowed drivers to improperly access uninitialized
   VMAs. It replaces the error_hook with a simple error-code field and
   updates the memory char driver accordingly

 - "mm/damon: minor improvements for code readability and tests"
   (SeongJae Park)

 - "mm/damon: fix macro arguments and clarify quota goals doc" (Maksym
   Shcherba)

 - "userfaultfd: merge fs/userfaultfd.c into mm/userfaultfd.c" (Mike
   Rapoport)

 - "mm/mglru: improve reclaim loop and dirty folio" (Kairui Song and
   others)

   Clean up and slightly improves MGLRU's reclaim loop and dirty
   writeback handling. Large performance improvements are measured

 - "use vma locks for proc/pid/{smaps|numa_maps} reads" (Suren
   Baghdasaryan)

   Use per-vma locks when reading /proc/pid/smaps and numa_maps similar
   to reduce contention on central mmap_lock

 - "refactors thpsize_shmem_enabled_store() and thpsize_shmem_enabled_show()"
   (Ran Xiaokai)

   Some cleanup work in the THP code

 - "selftests/memfd: fix compilation warnings" (Konstantin Khorenko)

   Fix a few build glitches in the memfd selftest code.

 - "memcg: shrink obj_stock_pcp and cache multiple objcgs" (Shakeel
   Butt)

   Resolve a 68% performance regression caused by NUMA-node cache
   thrashing around struct obj_stock_pcp by shrinking its existing
   fields and expanding it into a multi-slot array that caches up to
   five obj_cgroup pointers per CPU, allowing per-node variants of the
   same memcg to coexist within a single 64-byte cache line.

 - "zram: writeback fixes" (Sergey Senozhatsky)

   address a couple of unrelated zram writeback issues

 - "mm: switch THP shrinker to list_lru" (Johannes Weiner)

   Resolve NUMA-awareness issues and streamlines callsite interaction by
   refactoring and extending the list_lru API to completely replace the
   complex, open-coded deferred split queue for Transparent Huge Pages

 - "mm: improve large folio readahead for exec memory" (Usama Arif)

   Improve large-folio readahead on systems like 64K-page arm64 by
   preventing the mmap_miss check from permanently disabling
   target-oriented VM_EXEC readahead, and by generalizing the
   force_thp_readahead gate to support mappings with any usefully large
   maximum folio order under the cache cap.

 - "userfaultfd/pagemap: pre-existing fixes" (Kiryl Shutsemau)

   Fix a bunch of minor issues in the userfaultfd/pagemap, all of which
   were flagged by Sashiko review of proposed new material

 - "mm/sparse-vmemmap: Provide generic vmemmap_set_pmd() and
   vmemmap_check_pmd()" (Muchun Song)

   Provide generic versions of these two functions so the four
   arch-specific implementations can be removed.

Armin Wolf 2682d63086 leds: Introduce the multi_max_intensity sysfs attribute 
Some multicolor LEDs support global brightness control in hardware,
meaning that the maximum intensity of the color components is not
connected to the maximum global brightness. Such LEDs cannot be
described properly by the current multicolor LED class interface,
because it assumes that the maximum intensity of each color component
is described by the maximum global brightness of the LED.

Fix this by introducing a new sysfs attribute called
"multi_max_intensity" holding the maximum intensity values for the
color components of a multicolor LED class device. Drivers can use
the new max_intensity field inside struct mc_subled to tell the
multicolor LED class code about those values. Intensity values written
by userspace applications will be limited to this maximum value.

Drivers for multicolor LEDs that do not support global brightness
control in hardware might still want to use the maximum global LED
brightness supplied via devicetree as the maximum intensity of each
individual color component. Such drivers should set max_intensity
to 0 so that the multicolor LED core can act accordingly.

The lp50xx and ncp5623 LED drivers already use hardware-based control
for the global LED brightness. Modify those drivers to correctly
initalize .max_intensity to avoid being limited to the maximum global
brightness supplied via devicetree.

Linus Torvalds b85966adbf Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next 
Pull networking updates from Jakub Kicinski:
 "Core & protocols:

   - Work on removing rtnl_lock protection throughout the stack
     continues. In this chapter:
       - don't use rtnl_lock for IPv6 multicast routing configuration
       - don't take rtnl_lock in ethtool for modern drivers
       - prepare Qdisc dump callbacks for rtnl_lock removal

   - Support dumping just ifindex + name of all interfaces, under RCU.
     It's a common operation for Netlink CLI tools (when translating
     names to ifindexes) and previously required full rtnl_lock.

   - Support dumping qdiscs and page pools for a specific netdev. Even
     tho user space wants a dump of all netdevs, most of the time, the
     OOO programming model results in repeating the dump for each
     netdev. Which, in absence of a cache, leads to a O(n^2) behavior.

   - Flush nexthops once on multi-nexthop removal (e.g. when device goes
     down), another O(n^2) -> O(n) improvement.

   - Rehash locally generated traffic to a different nexthop on
     retransmit timeout.

   - Honor oif when choosing nexthop for locally generated IPv6 traffic.

   - Convert TCP Auth Option to crypto library, and drop non-RFC algos.

   - Increase subflow limits in MPTCP to 64 and endpoint limit to 256.

   - Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
     to selectively skip reporting of the standard TCP Timestamp option,
     because they won't fit into the header space together (12 + 30 >
     40).

   - Support using bridge neighbor suppression, Duplicate Address
     Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
     deployments, e.g. VXLAN fabrics (IPv4 and IPv6).

   - Improve link state reporting for upper netdevs (e.g. macvlan) over
     tunnel devices (again, mostly for EVPN deployments).

   - Support binding GENEVE tunnels to a local address.

   - Speed up UDP tunnel destruction (remove one synchronize_rcu()).

   - Support exponential field encoding in multicast (IGMPv3 and MLDv2).

   - Support attaching PSP crypto offload to containers (veth, netkit).

   - Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
     migrating individual IPsec SAs independently of their policies.

     The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
     migration, lacks SPI for unique SA identification, and cannot
     express reqid changes or migrate Transport mode selectors.

     The new interface identifies the SA via SPI and mark, supports
     reqid changes, address family changes, encap removal, and uses an
     atomic create+install flow under x->lock to prevent SN/IV reuse
     during AEAD SA migration.

   - Implement GRO/GSO support for PPPoE.

   - Convert sockopt callbacks in a number of protocols to iov_iter.

  Cross-tree stuff:

   - Remove support for Crypto TFM cloning (unblocked after the TCP Auth
     Option rework). This feature regressed performance for all crypto
     API users, since it changed crypto transformation objects into
     reference-counted objects.

   - Add FCrypt-PCBC implementation to rxrpc and remove it from the
     global crypto API as obsolete and insecure.

  Wireless:

   - Major rework of station bandwidth handling, fixing issues with
     lower capability than AP.

   - Cleanups for EMLSR spec issues (drafts differed).

   - More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
     schedule improvements, multi-station etc.)

   - Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
     (e.g. non-primary channel access, UHR DBE support).

   - Fine Timing Measurement ranging (i.e. distance measurement) APIs.

  Netfilter:

   - Use per-rule hash initval in nf_conncount. This avoids unnecessary
     lock contention with short keys (e.g. conntrack zones) in different
     namespaces.

   - Various safety improvements, both in packet parsing and object
     lifetimes. Notably add refcounts to conntrack timeout policy.

  Deletions:

   - Remove TLS + sockmap integration. TLS wants to pin user pages to
     avoid a copy, and sockmap wants to write to the input stream. More
     work on this integration is clearly needed, and we can't find any
     users (original author admitted that they never deployed it).

   - Remove support for TLS offload with TCP Offload Engine (the far
     more common opportunistic offload is retained). The locking looks
     unfixable (driver sleeps under TCP spin locks) and people from the
     vendor that added this are AWOL.

   - Remove more ATM code, trying to leave behind only what PPPoATM
     needs, AAL5 and br2684 with permanent circuits.

   - Remove AppleTalk. Let it join hamradio in our out of tree protocol
     graveyard, I mean, repository.

   - Disable 32-bit x_tables compatibility (32bit binaries on 64bit
     kernel) interface in user namespaces. To be deleted completely,
     soon.

   - Remove 5/10 MHz support from cfg80211/mac80211.

           - expose more per-queue stats over the standard API

Dariusz Figzał 711104ab5e platform/x86: asus-wmi: add keystone dongle support 
The ASUS Keystone is a physical NFC-like dongle that slots into supported
ASUS laptops. The EC fires WMI notify code 0xB4 on insert/remove events.

Expose the current insert state via a sysfs attribute by querying WMI
device ID 0x00120091 (DSTS). This devid does not follow the standard DSTS
convention: PRESENCE_BIT (0x00010000) encodes the insert state rather than
feature presence, and STATUS_BIT is never set. Presence of a keystone slot
is detected by a successful DSTS call.

Ferdinand Schwenk 8250814145 hwmon: Add update_interval_us chip attribute 
Some hardware monitoring chips support update intervals below one
millisecond. The existing update_interval attribute uses millisecond
granularity, which causes sub-millisecond steps to round to the same
value and become inaccessible from userspace.

Introduce update_interval_us, a companion chip-level attribute that
expresses the same update interval in microseconds. Drivers
implementing this attribute should also implement update_interval for
compatibility with millisecond-based userspace interfaces.

Junyuan Wang fb98254a5e crypto: qat - add KPT support for GEN6 devices 
Add support for Intel Key Protection Technology (KPT) on QAT GEN6
devices.

KPT protects private keys from exposure by keeping them wrapped
(encrypted) while in use, in-flight, and at rest. Keys remain in wrapped
form and are not exposed in plaintext in host memory. This feature
operates outside of the Linux crypto framework and kernel keyring.

Extend the firmware admin interface to enable and configure KPT. During
device initialisation, if KPT is enabled, the driver sends an admin
message to firmware to enable KPT mode and configure parameters such as
the maximum number of SWK (Symmetric Wrapping Key) slots and the SWK
time-to-live (TTL).

Expose KPT configuration via a new sysfs attribute group, "qat_kpt", and
add ABI documentation.

Chao Gao 885afcf7c8 coco/tdx-host: Expose P-SEAMLDR information via sysfs 
TDX module updates require userspace to select the appropriate module
to load. Expose necessary information to facilitate this decision. Two
values are needed:

- P-SEAMLDR version: for compatibility checks between TDX module and
		     P-SEAMLDR
- num_remaining_updates: indicates how many updates can be performed

Expose them as tdx-host device attributes visible only when updates
are supported.

Note that the underlying P-SEAMLDR attributes are available regardless
of update support; this only restricts their visibility to userspace.

Chao Gao 6fe8a33fdb coco/tdx-host: Expose TDX module version 
For TDX module updates, userspace needs to select compatible update
versions based on the current module version.

For example, the 1.5.x series runs on Sapphire Rapids but not Granite
Rapids, which needs 2.0.x. Updates are also constrained by version
distance, so a 1.5.6 module might permit updates to 1.5.7 but not to
1.5.20.

Start the process of punting the version selection logic to userspace.
Expose the TDX module version in the new faux device.

Define TDX_VERSION_FMT macro for the TDX version format since it will be
used multiple times. Also convert an existing print statement to use it.

== Background ==

For posterity, here's what other firmware mechanisms do:

1. AMD SEV leverages an existing PCI device for the PSP to expose
   metadata. TDX uses a faux device as it doesn't have PCI device
   in its architecture.

2. Microcode uses per-CPU virtual devices to report microcode revisions
   because CPUs can have different revisions. But, there is only a
   single TDX module, so exposing the TDX module version through a global
   TDX faux device is appropriate

3. ARM's CCA implementation isn't in-tree yet, but will likely follow a
   similar faux device approach, though it's unclear whether they need
   to expose firmware version information

Johnson Tsai 384cc80f30 wifi: rtw89: usb: add serial_number and uuid sysfs attributes for 0x28de:0x2432 
Expose the device's Serial Number (SN) and UUID from EFUSE via two
read-only sysfs attributes, `serial_number` and `uuid`, on the ieee80211
phy device under the `rtw89_usb` attribute group.

This hardware identification information is essential for user-space
applications to uniquely identify, track, and manage specific Wi-Fi
adapters. For example, in automated factory provisioning or device
management systems, user-space tools rely on the EFUSE serial number and
UUID to bind configurations to specific physical adapters. Currently,
standard wireless APIs do not expose this low-level hardware
information, making these sysfs nodes the only viable solution for
user space to extract this data.

The attributes are gated behind a new RTW89_QUIRK_HW_INFO_SYSFS quirk,
enabled only for the VID 0x28de / PID 0x2432 device via the
dev_id_quirks field in rtw89_driver_info.

Example usage from user-space:
  $ cat /sys/class/ieee80211/phy0/rtw89_usb/serial_number
  3642000123
  $ cat /sys/class/ieee80211/phy0/rtw89_usb/uuid

Ronak Jain 8ebebccf15 Documentation: ABI: add sysfs interface for ZynqMP CSU registers 
Document the new sysfs interface that exposes Configuration Security
Unit (CSU) registers through the zynqmp-firmware driver.

The interface is available under:

  /sys/devices/platform/firmware:zynqmp-firmware/csu_registers/

The CSU registers are discovered at boot time using the PM_QUERY_DATA
firmware API. The following registers are currently supported:

  - multiboot     (CSU_MULTI_BOOT)
  - idcode        (CSU_IDCODE, read-only)
  - pcap-status   (CSU_PCAP_STATUS, read-only)

Read operations use the existing IOCTL_READ_REG firmware interface,
while write operations use IOCTL_MASK_WRITE_REG.

Access control is enforced by the firmware. Write attempts to
read-only registers are rejected by firmware even though the sysfs file
permissions allow writes.

Document the ABI entry accordingly.

Mika Westerberg 6db21d817b thunderbolt: Add support for USB4STREAM 
Introduce USB4STREAM protocol and Linux implementation. This allows two
(or more) hosts to transfer data directly over Thunderbolt/USB4 cable
through a character device without need to go through the network stack.

Any application that supports read(2) and write(2) in some form should
be able to use the device without changes. The data is sent out to the
other side over a tunnel inside Thunderbolt/USB4 fabric. The character
device is called /dev/tbstreamX where X is the minor number starting
from 0.

All stream devices need to be configured first. This is done through
ConfigFS interface. There can be multiple streams at the same time (this
depends on number of DMA rings and available HopIDs) and a single stream
supports traffic in both directions. For example there could be an
application that uses one stream as control channel and another one as
bi-directional data channel.

A real use-case for this is to take a backup as a part of recovery
initramfs tooling (no need to setup networking or have ssh or similar
tooling as part of the initramfs). Say we want to backup the disk of
host1 to host2. First Thunderbolt/USB4 cable is connected between the
hosts (there can be devices in the middle too) then the receiving side
configures the stream:

  host2 # mkdir /sys/kernel/config/thunderbolt/stream/0-1.0
  host2 # mkdir /sys/kernel/config/thunderbolt/stream/0-1.0/backup
  host2 # echo -1 > /sys/kernel/config/thunderbolt/stream/0-1.0/backup/in_hopid
  host2 # echo -1 > /sys/kernel/config/thunderbolt/stream/0-1.0/backup/out_hopid

We use automatic HopID allocation (writing -1 to HopIDs) for simplicity.
From this point forward the /dev/tbstream0 can be used pretty much as
regular file:

  host2 # dd if=/dev/tbstream0 of=/tmp/host1.nvme0n1.backup-$(date +%F) bs=256k

The host that is being backed up then configures the stream accordingly:

  host1 # mkdir /sys/kernel/config/thunderbolt/stream/0-503.0
  host1 # mkdir /sys/kernel/config/thunderbolt/stream/0-503.0/backup

Here we take advantage of the fact that host2 also announces the active
streams through XDomain properties so the name "backup" gives us the
HopIDs. It is also possible to configure them manually in the same way
we did for host2.

Then it is just a matter of copying the data over:

  host1 # dd if=/dev/nvme0n1 of=/dev/tbstream0 bs=256k

Similarly it is possible to transfer parts of the filesystem. For
example copy contents of mydir over to the host2:

  host2 # gunzip < /dev/tbstream0 | tar xf -
  host1 # tar cf - mydir | gzip > /dev/tbstream0

Other end of the spectrum use-case is "borrowing" laptop (host1) camera
to desktop (host2):

  host2 # gst-launch-1.0 filesrc location=/dev/tbstream0 ! jpegdec ! videoconvert ! \
                         autovideosink

  host1 # gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080 ! \
                         jpegenc quality=90 ! filesink location=/dev/tbstream0

Once the streams are no longer needed they can be removed:

  host1 # cd /sys/kernel/config/thunderbolt/stream/
  host1 # rmdir -p 0-503.0/backup

  host2 # cd /sys/kernel/config/thunderbolt/stream
  host2 # rmdir -p 0-1.0/backup

Stephen Smalley ad1ac3d740 selinux: prune /sys/fs/selinux/user 
Remove the previously deprecated /sys/fs/selinux/user interface aside
from a residual stub for userspace compatibility.

Commit d7b6918e22 ("selinux: Deprecate /sys/fs/selinux/user") started
the deprecation process for /sys/fs/selinux/user:

    The selinuxfs "user" node allows userspace to request a list
    of security contexts that can be reached for a given SELinux
    user from a given starting context. This was used by libselinux
    when various login-style programs requested contexts for
    users, but libselinux stopped using it in 2020.
    Kernel support will be removed no sooner than Dec 2025.

A pr_warn() message has been in place since Linux v6.13, and a 5
second sleep was introduced since Linux v6.17 to help make it more
noticeable.

We are now past the stated deadline of Dec 2025, so remove the
underlying functionality and replace it with a stub that returns a
'0\0' buffer to avoid breaking userspace. This also avoids a local DoS
from logspam and an uninterruptible sleep delay.

Andrzej Kacprowski 7455a0583a accel/ivpu: Add support for limiting NPU frequency 
Add configurable frequency limits to allow users to constrain the NPU
operating frequency range for power and thermal management. This support
requires firmware API version 3.34.0 or newer.

New sysfs interface:

The freq/ subdirectory contains the following attributes:

- hw_min_freq: Minimum frequency supported by hardware (read-only)
- hw_max_freq: Maximum frequency supported by hardware (read-only)
- hw_efficient_freq: Hardware's optimal operating frequency (read-only)
- current_freq: Current NPU frequency in MHz (read-only)
- set_min_freq: Configure minimum operating frequency (50XX+ devices)
- set_max_freq: Configure maximum operating frequency (50XX+ devices)

Legacy attributes npu_max_frequency_mhz and npu_current_frequency_mhz
are maintained for backward compatibility.

Implementation details:

- Frequency configuration is communicated to firmware via JSM messages
- User-specified frequency values are clamped to hardware limits
- Power-efficient frequency (pn_ratio) is adjusted dynamically to stay
  within the configured range
- Frequency configuration is initialized during device boot
- The JSM API header is updated to version 3.34.0 to support the new
  VPU_JSM_MSG_FREQ_CONFIG firmware message

Added description for the sysfs attributes in the Documentation/ABI.
