Mime-Version: 1.0 Message-ID: <2012073015244959361219@gmail.com> List-Id: XFS Filesystem from SGI List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: xfs-bounces@oss.sgi.com Errors-To: xfs-bounces@oss.sgi.com To: axboe , "konrad.wilk" , "chris.mason" , viro , tytso , "adilger.kernel" , shaggy , mfasheh , jlbec , bpm , elder Cc: jfs-discussion , linux-kernel , xfs , linux-fsdevel , linux-ext4 , linux-btrfs Because call bio_alloc, the bi_rw is zero by default,but in bio_add_page used the bi_rw. So evalue bi_rw.
