Subject: Re: [PATCH RT 2/5] a few open coded completions
Date: Wed, 11 Dec 2013 14:54:00 -0500 [thread overview]
Message-ID: <20131211145400.1b355ce4@gandalf.local.home> (raw)
In-Reply-To: <20131211004643.325379918@goodmis.org>
Here's the new patch for 3.8-rt.

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Mon, 28 Oct 2013 11:50:06 +0100
Subject: [PATCH] swait: Add a few more users
The wait-simple queue is lighter weight and more efficient than the full
wait queue, and may be used in atomic context on PREEMPT_RT.
Fix up some places that needed to call the swait_*() functions instead
of the wait_*() functions.
