Merge tag 'vfs-6.18-rc7.fixes' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Browse Source 
Pull vfs fixes from Christian Brauner:

 - Fix unitialized variable in statmount_string()

 - Fix hostfs mounting when passing host root during boot

 - Fix dynamic lookup to fail on cell lookup failure

 - Fix missing file type when reading bfs inodes from disk

 - Enforce checking of sb_min_blocksize() calls and update all callers
   accordingly

 - Restore write access before closing files opened by open_exec() in
   binfmt_misc

 - Always freeze efivarfs during suspend/hibernate cycles

 - Fix statmount()'s and listmount()'s grab_requested_mnt_ns() helper to
   actually allow mount namespace file descriptor in addition to mount
   namespace ids

 - Fix tmpfs remount when noswap is specified

 - Switch Landlock to iput_not_last() to remove false-positives from
   might_sleep() annotations in iput()

 - Remove dead node_to_mnt_ns() code

 - Ensure that per-queue kobjects are successfully created
