Description

I thought this was a repeat of #10164, but then noticed that the dirfrag objects were deleted once the client unmounted.

I've added a workaround for this in the new mds_flush test task, which checks that deletion results in objects going away after a flush.

From looking at client logs, it appears that the client simply does not release the capability on a directory when it deletes it, so the MDS can't purge the stray directory.

This was merged to master in commit:e9a29c58b6d40933afbf711afcf7b872b4005585; does it need a backport?

do we need to backport this. the directory will be deleted when all of its child dentries get trimmed from the cache

I wouldn't bother backporting: the symptom is just some dir objects that don't get cleaned up until next client unmount, so it doesn't break the world for users.
