Subject[GIT PULL] Block fixes for 3.13-rc
Hi Linus,

A small collection of fixes for the current series. It contains:

- A fix for a use-after-free of a request in blk-mq. From Ming Lei.

- A fix for a blk-mq bug that could attempt to dereference a NULL rq if
allocation failed.

- Two xen-blkfront small fixes.

- Cleanup of submit_bio_wait() type uses in the kernel, unifying that.
From Kent.

- A fix for 32-bit blkg_rwstat reading. I apologize for this one looking
mangled in the shortlog, it's entirely my fault for missing an empty
line between the description and body of the text.

Please pull!

block: xen-blkfront: Fix possible NULL ptr dereference

Hong Zhiguo (1):
Update of blkg_stat and blkg_rwstat may happen in bh context. While u64_stats_fetch_retry is only preempt_disable on 32bit UP system. This is not enough to avoid preemption by bh and may read strange 64 bit value.
