Subject: [PATCH] locks: fix generic_delete_lease tracepoint to use victim pointer
Date: Sat,  7 Mar 2015 07:51:10 -0500	[thread overview]
Message-ID: <1425732670-4890-1-git-send-email-jeff.layton@primarydata.com> (raw)

It's possible that "fl" won't point at a valid lock at this point, so
have it instead point at "victim" which is either a valid lock or NULL.
