Subject: [PATCH 34/39] scsi: partially stub out scsi_adjust_queue_depth when using blk-mq
Date: Mon, 17 Mar 2014 06:28:07 -0700 [thread overview]
Message-ID: <20140317133136.569692646@bombadil.infradead.org> (raw)
In-Reply-To: 20140317132733.789623766@bombadil.infradead.org
[-- Attachment #1: 0034-scsi-partially-stub-out-scsi_adjust_queue_depth-when.patch --]
[-- Type: text/plain, Size: 796 bytes --]
This will have to be funnelled to blk-mq directly, but skip it for now.
