Subject: [Kernel-janitors] [PATCH 2.6.9-rc2 7/16] scsi/osst: replace
Date: Mon, 27 Sep 2004 18:21:58 +0000	[thread overview]
Message-ID: <20040927182158.GV1676@us.ibm.com> (raw)

Any comments would be appreciated.

Description: Use msleep_interruptible() instead of
schedule_timeout() to guarantee the task delays as expected.
