Merge tag 'vfs-6.18-rc1.async' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

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

   - Add lookup_one_positive_killable() which allows overlayfs to
     perform lookup that won't block on a fatal signal

   - Unify the mount idmap handling in struct renamedata as a rename can
     only happen within a single mount

   - Introduce kern_path_parent() for audit which sets the path to the
     parent and returns a dentry for the target without holding any
     locks on return

   - Rename kern_path_locked() as it is only used to prepare for the
     removal of an object from the filesystem:

	kern_path_locked()    => start_removing_path()
	kern_path_create()    => start_creating_path()
	user_path_create()    => start_creating_user_path()
	user_path_locked_at() => start_removing_user_path_at()
	done_path_create()    => end_creating_path()
	NA                    => end_removing_path()"

* tag 'vfs-6.18-rc1.async' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  debugfs: rename start_creating() to debugfs_start_creating()
  VFS: rename kern_path_locked() and related functions.
  VFS/audit: introduce kern_path_parent() for audit
  VFS: unify old_mnt_idmap and new_mnt_idmap in renamedata
  VFS: discard err2 in filename_create()
  VFS/ovl: add lookup_one_positive_killable()
