3.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Josef Bacik <jba...@fusionio.com>
commit 50f1319cb5f7690e4d9de18d1a75ea89296d0e53 upstream.
I was getting warnings when running find ./ -type f -exec btrfs fi defrag -f {}
\; from record_one_backref because ret was set. Turns out it was because it was
set to 1 because the search slot didn't come out exact and we never reset it.
So reset it to 0 right after the search so we don't leak this and get
uneccessary warnings. Thanks,
