[GIT PULL] block bits for 2.6.34

[GIT PULL] block bits for 2.6.34

[Jens Axboe]

Hi Linus,

I apologize for this being somewhat larger than it usually is at that
point, it's mostly due to testing which has held off the submission
longer than I really wanted. But it's mostly good fixes, the odd one out
is the VFS writeback patch which makes the sb pinning a lot nicer. It's
been in -next for a long time, well over a month. So I consider it safe.

The drbd patches are largely focused on making 4kb block sizes work, it
would oops before.

The rest is mostly regression fixes and bug fixes. 2 of the fixes
already went in through Andrew the other day, but I did a merge check
and it'll pull cleanly. So I have not pulled in your latest tree. The
other pull in was to resolve a merge conflict a few weeks ago.

So please pull, thanks.
