[GIT PULL] Block bits for 3.0-rc2

[GIT PULL] Block bits for 3.0-rc2

[Jens Axboe]

Hi Linus,

A collection of smallish fixes for -rc2.

- One bio documentation improvement, that I see Al already pushed out.
  Should be identical, if not I'm sure you are up to the merge.

- Two bug fixes for the XEN blkback driver.

- A revert of a patch that caused a regression in sysfs discard
  alignment display.

- Further patches from Namhyung Kim, giving nbd the same fixup treatment
  for max_part oopsable conditions. Also fixes an ancient bug in there
  were the recvmsg() flags aren't correctly passed in.

- Two fixes from Paul Bolle, removing an if that was always false and
  correcting usage of list_entry() to hlist_entry() (cosmetical).

- A blkdev_get() fixup from Tejun.

Please pull.
