[GIT PUL] block driver updates for 2.6.37-rc1

[Jens Axboe <jaxboe@fusionio.com>]

Hi Linus,

A collection of block driver updates for 2.6.37-rc1. Biggest chunk is a
huge chunk of drbd updates and fixes, cciss follows close behind with a
series of nice cleanups.

On the fast moving side of floppy, a few patches from Vivek and myself
to get rid of queue sharing. Once this work is completely, we can remove
some of the ugly hacks in bdi_register() and friends.

Please pull.
