Subject: [PATCH 05/12] block_dev: get bdev inode bdi directly from the block device
Date: Thu,  8 Jan 2015 18:45:26 +0100	[thread overview]
Message-ID: <1420739133-27514-6-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1420739133-27514-1-git-send-email-hch-jcswGhMUV9g@public.gmane.org>

Directly grab the backing_dev_info from the request_queue instead of
detouring through the address_space.
