From: mchristi@redhat.com Subject: [PATCH 03/35] block, fs, mm, drivers: set bi_op to REQ_OP Date: Mon, 11 Jan 2016 14:21:01 -0600 Message-ID: <1452543693-4440-4-git-send-email-mchristi@redhat.com> References: <1452543693-4440-1-git-send-email-mchristi@redhat.com> Cc: Mike Christie To: linux-f2fs-devel@lists.sourceforge.net, linux-ext4@vger.kernel.org, konrad.wilk@oracle.com, drbd-dev@lists.linbit.com, philipp.reisner@linbit.com, lars.ellenberg@linbit.com, linux-raid@vger.kernel.org, dm-devel@redhat.com, linux-fsdevel@vger.kernel.org, linux-bcache@vger.kernel.org, linux-block@vger.kernel.org, linux-kernel@vger.kernel.org, linux-scsi@vger.kernel.org, linux-mtd@lists.infradead.org, target-devel@vger.kernel.org, linux-btrfs@vger.kernel.org, osd-dev@open-osd.org, xfs@oss.sgi.com, ocfs2-devel@oss.oracle.com Return-path: In-Reply-To: <1452543693-4440-1-git-send-email-mchristi@redhat.com> Sender: linux-scsi-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org From: Mike Christie This patch converts the simple bi_rw use cases in the block, drivers, mm and fs code to use bi_op for a REQ_OP and bi_rw for rq_flag_bits. These should be simple one liner cases, so I just did them in one patch. The next patches handle the more complicated cases in a module per patch.
