Subject: [PATCH 01/15] block: don't overwrite bdi->state after bdi_init() has been run

Message-ID: <1244811255-5391-2-git-send-email-jens.axboe@oracle.com> (raw)
In-Reply-To: <1244811255-5391-1-git-send-email-jens.axboe@oracle.com>

Move the defaults to where we do the init of the backing_dev_info.
