Subject: [GIT PULL] vfs fixes

Hey Linus,

/* Summary */

This contains a few fixes for this cycle:

- 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.
