Subject: [patch 02/26] char/cyclades: replace schedule_timeout() with msleep_interruptible()
Date: Thu, 23 Sep 2004 22:24:58 +0200 [thread overview]
Message-ID: <E1CAa9D-0007mL-31@sputnik> (raw)
Any comments would be appreciated.
Description: Use msleep_interruptible() instead of schedule_timeout()
to guarantee the task delays as expected.
