Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"Outside of bcache (which really isn't super big), these are all
few-liners. There are a few important fixes in here:
- Fix blk pm sleeping when holding the queue lock
- A small collection of bcache fixes that have been done and tested
since bcache was included in this merge window.
- A fix for a raid5 regression introduced with the bio changes.
- Two important fixes for mtip32xx, fixing an oops and potential data
corruption (or hang) due to wrong bio iteration on stacked devices."
