Applied to the vfs-6.19.directory.delegations branch of the vfs/vfs.git tree.

Please report any outstanding bugs that were missed during review in a
new review to the original patch series allowing us to drop it.

patch has now been applied. If possible patch trailers will be updated.

trailer updates or similar. If in doubt, please check the listed branch.
