Subject: Re: [PATCH scsi-misc-2.6 03/07] scsi: replace scsi_queue_insert() usages with scsi_retry_command()
Date: Tue, 12 Apr 2005 21:52:36 +0900 (KST) [thread overview]
Message-ID: <20050412125219.D4AAB938@htj.dyndns.org> (raw)
In-Reply-To: <20050412125219.88E5C1F6@htj.dyndns.org>
03_scsi_requeue_use_scsi_retry_command_instead_of_scsi_queue_insert.patch
There are two users of scsi_queue_insert() left now. One in
scsi_softirq() and the other in scsi_eh_flush_done_q(). The
only additional functionality of scsi_queue_insert() used is
setting device_blocked on ADD_TO_MLQUEUE case in
scsi_softirq().
Open code device_blocked setting and replace
scsi_queue_insert() with scsi_retry_command() in both cases.
