Subject: [RESEND PATCH V5 21/33] fs: conver to bio_for_each_page_all2
Date: Fri, 25 May 2018 11:46:09 +0800	[thread overview]
Message-ID: <20180525034621.31147-22-ming.lei@redhat.com> (raw)
In-Reply-To: <20180525034621.31147-1-ming.lei@redhat.com>

bio_for_each_page_all() can't be used any more after multipage bvec is
enabled, so we have to convert to bio_for_each_page_all2().
