From 0ea60b5ad8c3630e8f44c443f173d841be7fc701 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 9 Jan 2006 14:45:10 +0100 Subject: [BLOCK] bio: init ->bi_bdev in bio_init() For SG_IO requests, bio->bi_bdev may not be explicitly initialized. So make bio_init() clear the field to make sure it's always NULL or valid.
