https://bugzilla.kernel.org/show_bug.cgi?id=16312 --- Comment #30 from Jan Kara <jack@xxxxxxx> 2010-09-16 18:13:21 --- OK, Tejun, I finally read the code. So you are right that the patch doesn't solve the race. The race seems to be in block/genhd.c:add_disk(). Once we call register_disk(), device can be successfully opened (get_gendisk() from blkdev_open() will succeed as soon as disk's kobject exists). But until we call bdi_register_dev(), backing dev isn't properly initialized and thus can see the warning. This also explains why Larry is able to see the warning even with your patch. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
