  "message": "block: Fix race during disk initialization\n\nWhen a new disk is being discovered, add_disk() first ties the bdev to gendisk\n(via register_disk()-\u003eblkdev_get()) and only after that calls\nbdi_register_bdev(). Because register_disk() also creates disk\u0027s kobject, it\ncan happen that userspace manages to open and modify the device\u0027s data (or\ninode) before its BDI is properly initialized leading to a warning in\n__mark_inode_dirty().\n\nFix the problem by registering BDI early enough.\n\nThis patch addresses https://bugzilla.kernel.org/show_bug.cgi?id\u003d16312\n\nCc: stable@kernel.org\nReported-by: Larry Finger \u003cLarry.Finger@lwfinger.net\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Jens Axboe \u003cjaxboe@fusionio.com\u003e\n",
