Subject: [24/34] slow-work: use get_ref wrapper instead of directly calling get_ref

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Dave Airlie <airlied@...hat.com>

commit 88be12c440cfa2fa3f5be83507360aac9ea1c54e upstream.

Otherwise we can get an oops if the user has no get_ref/put_ref
requirement.
