Subject: [PATCH 7/7] sched: Convert the only user of cond_resched_bkl to use cond_resched()
Date: Thu, 16 Jul 2009 02:28:14 -0400	[thread overview]
Message-ID: <1247725694-6082-7-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1247725694-6082-1-git-send-email-fweisbec@gmail.com>

fs/locks.c:flock_lock_file() is the only user of cond_resched_bkl()

This helper doesn't do anything more than cond_resched(). The latter
naming is enough to explain that we are rescheduling if needed.

The bkl suffix suggests another semantics but it's actually
a synonym of cond_resched().
