[patch 13/16] net/s2io.c: replace schedule_timeout() with msleep()

To: netdev@xxxxxxxxxxx
Subject: [patch 13/16] net/s2io.c: replace schedule_timeout() with msleep()
From: janitor@xxxxxxxxxxxxxx
Date: Wed, 01 Sep 2004 23:03:43 +0200
Cc: jgarzik@xxxxxxxxx, janitor@xxxxxxxxxxxxxx
Sender: netdev-bounce@xxxxxxxxxxx





I would appreciate any comments from the janitor@sternweltens list. 



Description: Use msleep() instead of schedule_timeout() to guarantee
the task delays for the desired time.
