[GIT PULL] block fixes for 2.6.39-rc3

[GIT PULL] block fixes for 2.6.39-rc3

[Jens Axboe]

Hi Linus,

With this in, I believe the only regression there's left is the one in
IDE which seems to be due to endless media events being generated. In
this round:

- Removal of the ->unplugged_fn(), as MD could not really use it. This
  adds a callback list instead, which MD can use to get notification on
  the level it requires.

- Neils MD fixes to fix with write intent bitmap hanging.

- Small fixup to use kblockd workqueue for the delay work, that was an
  oversight (it used the system workqueue instead).

- Small improvement to drop the queue lock before doing the async
  kblockd wakeup.

Please pull.
