Subject: [PATCH 3.12 107/118] Btrfs: reset intwrite on transaction abort

3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Josef Bacik <jbacik@...ionio.com>

commit e0228285a8cad70e4b7b4833cc650e36ecd8de89 upstream.

If we abort a transaction in the middle of a commit we weren't undoing the
intwrite locking.  This patch fixes that problem.
