[PATCH 5.5 216/257] nfsd: fsnotify on rmdir under nfsd/clients/

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

From: J. Bruce Fields <bfields@xxxxxxxxxx>

commit 69afd267982e733a555fede4e85fe30329ed0588 upstream.

Userspace should be able to monitor nfsd/clients/ to see when clients
come and go, but we're failing to send fsnotify events.
