Subject: [PATCH 05/12] qla4xxx: Updated firmware ready timeout algorithm
Date: Tue, 6 Apr 2010 03:14:08 -0700 [thread overview]
Message-ID: <20100406101408.GL22922@linux-qf4p> (raw)
From: Vikas Chaudhary <vikas.chaudhary@qlogic.com>
Updated firmware ready timeout algorithm to prevent
long delays and use jiffies to time out instead of
counter. Also use msleep_interruptible instead of msleep.
