Subject: [PATCH net 0/2] strparser: Fix lockdep issue
Date: Thu, 28 Dec 2017 11:00:42 -0800	[thread overview]
Message-ID: <20171228190044.3748-1-tom@quantonium.net> (raw)

When sock_owned_by_user returns true in strparser. Fix is to add and
call sock_owned_by_user_nocheck since the check for owned by user is
not an error condition in this case.

Fixes: 43a0c6751a322847 ("strparser: Stream parser for messages")
