Subject: [PATCH 02/05] video: deferred io cleanup
Date: Fri, 19 Dec 2008 15:34:23 +0900 [thread overview]
Message-ID: <20081219063423.2703.88796.sendpatchset@rx1.opensource.se> (raw)
In-Reply-To: <20081219063359.2703.85817.sendpatchset@rx1.opensource.se>
From: Magnus Damm <damm@igel.co.jp>
Make sure the mmap callback is set to NULL in the deferred io
cleanup function. This way we can enable and disable deferred
io on the fly.
