Pull mount_setattr fix from Christian Brauner: "This makes an underlying idmapping assumption more explicit. We currently don't have any filesystems that support idmapped mounts which are mountable inside a user namespace, i.e. where s_user_ns != init_user_ns. That was a deliberate decision for now as userns root can just mount the filesystem themselves. Express this restriction explicitly and enforce it until there's a real use-case for this. This way we can notice it and will have a chance to adapt and audit our translation helpers and fstests appropriately if we need to support such filesystems" * tag 'fs.idmapped.mount_setattr.v5.13-rc3' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux: fs/mount_setattr: tighten permission checks
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.
