Subject: [PATCH 2/8] drivers/block/xen-blkback:Evalue bio->bi_rw after calling bio_alloc() and before calling bio_add_page().
Date: Mon, 30 Jul 2012 15:23:55 +0800 [thread overview]
Message-ID: <2012073015233873461213@gmail.com> (raw)
Because call bio_alloc, the bi_rw is zero by default,but in
bio_add_page used the bi_rw. So evalue bi_rw.
