Merge tag 'vfs-7.1-rc1.directory' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs directory updates from Christian Brauner:
 "Recently 'start_creating', 'start_removing', 'start_renaming' and
  related interfaces were added which combine the locking and the
  lookup.

  At that time many callers were changed to use the new interfaces.
  However there are still an assortment of places out side of the core
  vfs where the directory is locked explictly, whether with inode_lock()
  or lock_rename() or similar. These were missed in the first pass for
  an assortment of uninteresting reasons.

  This addresses the remaining places where explicit locking is used,
  and changes them to use the new interfaces, or otherwise removes the
  explicit locking.

  The biggest changes are in overlayfs. The other changes are quite
  simple, though maybe the cachefiles changes is the least simple of
  those"
