From 114f1ea408944f9515e45aa7452238fb15a1fa00 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Date: Mon, 25 Aug 2008 13:51:58 -0700 Subject: [PATCH] [SCSI] scsi_dh: no need to initialize rq->cmd with blk_get_request blk_get_request initializes rq->cmd (rq_init does) so the users don't need to do that.
