Subject: [patch 24/26] char/synclinkmp: replace schedule_timeout() with msleep_interruptible()
Date: Thu, 23 Sep 2004 22:26:01 +0200 [thread overview]
Message-ID: <E1CAaAD-0000P5-FU@sputnik> (raw)
Any comments would be appreciated.
Description: Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.
