Subject: [PATCH] dma-buf: drop the _rcu postfix on function names v3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The functions can be called both in _rcu context as well
as while holding the lock.
v2: add some kerneldoc as suggested by Daniel
v3: fix indentation
