Subject: [PATCH 6/9] mptfusion: task abort fix's
Date: Tue, 11 Jul 2006 17:32:33 -0600 [thread overview]
Message-ID: <20060711233233.GA8622@lsil.com> (raw)
Fix's to insure proper status is returned to midlayer
when a task abort failed to be aborted by controller
firmware.
Also sanity checks to prevent scsi cmd from being
double completed during error recovery.
