====================
rxrpc: Miscellaneous changes
Here are some miscellaneous changes for AF_RXRPC:
(1) Allow the list of local endpoints to be viewed through /proc.
(2) Switch to using refcount_t for refcounting.
(3) Fix a locking issue found by lockdep.
(4) Autogenerate tracing symbol enums from symbol->string maps to make it
easier to keep them in sync.
(5) Return an error to sendmsg() if a call it tried to set up failed.
Because it failed at this point, no notification will be generated for
recvmsg to pick up - but userspace still needs to know about the
failure.
(6) Fix the selection of abort codes generated by internal events. In
particular, rxrpc and kafs shouldn't be generating RX_USER_ABORT
unless it's because userspace did something to cancel a call.
(7) Adjust the interpretation and handling of certain ACK types to try and
detect NAT changes causing a call to seem to start mid-flow from a
different peer.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
