[GIT PULL] block bits for 2.6.37-rc1

[GIT PULL] block bits for 2.6.37-rc1

[Jens Axboe]

Hi Linus,

These are the fixes that have been collected since the initial push.
It's a bit larger than I would have liked, but the majority of the code
churn there is simply finishing the conversion away from the previous
REQ_HARDBARRIER. In summary:

- Two fixes for RCU locking around io priority support from Sergey and
  Daniel.

- Four fixes from me to report issues around missing validation of parts
  of the iov interface inside the block layer. All of these were
  reported by Dan Rosenberg.

- Removal of copy_io_context(), it's been unused since the AS io
  scheduler was killed from me.

- Documentational pruning of the AS io scheduler from Randy Dunlap.

- An kernel stack leak to userspace has been fixed up, missing a memset,
  from Vasiliy.

- Some fixes for cciss, mostly from HP but a fixup from me as well.

- Correct use of i_size_read() in various places instead of direct read
  of the inode size from Mike Snitzer.

- A drbd fix, and three patches to finish the transition to the new
  barrier scheme.

- Killing of REQ_HARDBARRIER in the block core from Christoph.

Please pull.
