Subject: [PATCH 18/20] ide: switch set_xfer_rate() to use REQ_TYPE_ATA_TASKFILE requests
Date: Sun, 9 Dec 2007 22:20:50 +0100 [thread overview]
Message-ID: <200712092220.51066.bzolnier@gmail.com> (raw)
Based on the earlier work by Tejun Heo.
Switch set_xfer_rate() to use REQ_TYPE_ATA_TASKFILE requests
and make ide_wait_cmd() static.
There should be no functionality changes caused by this patch.
