Date: Wed, 15 Sep 2004 22:54:42 +0000 [thread overview]
Message-ID: <20040915225442.GP5778@us.ibm.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1335 bytes --]
Any comments would be appreciated.
Description: Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.
