[GIT PULL] block fixes for 2.6.32-rc

[Jens Axboe <jens.axboe@oracle.com>]

Hi Linus,

Two small comment "regressions" from Alberto, which got screwed up
during some of the early .32 block commits. And then a fixup for the
previous sync hang fix, I had modified it slightly after it had been
tested. You should never do that... The last two fixes are for CFQ, both
fixing regressions introduced recently.

Please pull!
