Merge tag 'vfs-6.17-rc1.async.dir' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull async directory updates from Christian Brauner:
 "This contains preparatory changes for the asynchronous directory
  locking scheme.

  While the locking scheme is still very much controversial and we're
  still far away from landing any actual changes in that area the
  preparatory work that we've been upstreaming for a while now has been
  very useful. This is another set of minor changes and cleanups"
