#     Merge tag 'vfs-6.8-rc5.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
#     
#     Pull vfs fixes from Christian Brauner:
#     
#      - Fix performance regression introduced by moving the security
#        permission hook out of do_clone_file_range() and into its caller
#        vfs_clone_file_range().
#     
#        This causes the security hook to be called in situation were it
#        wasn't called before as the fast permission checks were left in
#        do_clone_file_range().
#     
#        Fix this by merging the two implementations back together and
#        restoring the old ordering: fast permission checks first, expensive
#        ones later.
#     
#      - Tweak mount_setattr() permission checking so that mount properties on
#        the real rootfs can be changed.
#     
#        When we added mount_setattr() we added additional checks compared to
#        legacy mount(2). If the mount had a parent then verify that the
#        caller and the mount namespace the mount is attached to match and if
#        not make sure that it's an anonymous mount.
#     
#        But the real rootfs falls into neither category. It is neither an
#        anoymous mount because it is obviously attached to the initial mount
#        namespace but it also obviously doesn't have a parent mount. So that
#        means legacy mount(2) allows changing mount properties on the real
#        rootfs but mount_setattr(2) blocks this. This causes regressions (See
#        the commit for details).
#     
#        Fix this by relaxing the check. If the mount has a parent or if it
#        isn't a detached mount, verify that the mount namespaces of the
#        caller and the mount are the same. Technically, we could probably
#        write this even simpler and check that the mount namespaces match if
#        it isn't a detached mount. But the slightly longer check makes it
#        clearer what conditions one needs to think about.
