Merge branch 'for-3.17/drivers' of git://git.kernel.dk/linux-block
Pull block driver changes from Jens Axboe: "Nothing out of the ordinary here, this pull request contains: - A big round of fixes for bcache from Kent Overstreet, Slava Pestov, and Surbhi Palande. No new features, just a lot of fixes. - The usual round of drbd updates from Andreas Gruenbacher, Lars Ellenberg, and Philipp Reisner. - virtio_blk was converted to blk-mq back in 3.13, but now Ming Lei has taken it one step further and added support for actually using more than one queue. - Addition of an explicit SG_FLAG_Q_AT_HEAD for block/bsg, to compliment the the default behavior of adding to the tail of the queue.
