block fixes for 2.6.39-rc3
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.
