# \[PATCH 2/8\] drivers/block/xen-blkback:Evalue bio-\>bi\_rw after calling bio\_alloc() and before calling bio\_add\_page(). - From: majianpeng \ - Date: 2012-07-30 07:23:55 - List: linux-ext4 - Page: https://ratatoskr.run/linux-ext4/2012/07/66157 - Thread: https://ratatoskr.run/linux-fsdevel/2012/07/66157/t.md ```text Because call bio_alloc, the bi_rw is zero by default,but in bio_add_page used the bi_rw. So evalue bi_rw.
