Subject: nfsd: fsnotify on rmdir under nfsd/clients/
X-Git-Tag: v5.6.5~47

nfsd: fsnotify on rmdir under nfsd/clients/

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.
