[GIT PULL] Block IO driver bits for 3.11

[Jens Axboe]

Hi Linus,

As I mentioned in the core block pull request, due to real life
circumstances the driver pull request would be late. Now it looks like
-rc2 late... On the plus side, apart form the rsxx update, these are all
things that I could argue could go in later in the cycle as they are
fixes and not features. So even though things are late, it's not ALL
bad.

The pull request contains:

- Updates to bcache, all bug fixes, from Kent.

- A pile of drbd bug fixes (no big features this time!).

- xen blk front/back fixes.

- rsxx driver updates, some of them deferred form 3.10. So should be
  well cooked by now.

Please pull!
