[GIT PULL] Final block fixes for 3.9

[GIT PULL] Final block fixes for 3.9

[Jens Axboe]

Hi Linus,

I've got a few smaller fixes queued up for 3.9 that should go in. The
major one is the loop regression, the others are nice fixes on their own
though. It contains:

- Fix for unitialized var in the block sysfs code, courtesy of Arnd and
  gcc-4.8.

- Two fixes for mtip32xx, fixing probe and command timeout. Also a debug
  measure that could have waited for 3.10, but it's driver only, so I
  let it slip in.

- Revert the loop partition cleanup fix, it could cause a deadlock on
  auto-teardown as part of umount. The fix is clear, but at this point
  we just want to revert it and get a real fix in for 3.10.

Please pull! Tag is signed.
