Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"A few small, but important fixes. Most of them are marked for stable
as well
- Fix failure to release a semaphore on error path in mtip32xx.
- Fix crashable condition in bio_get_nr_vecs().
- Don't mark end-of-disk buffers as mapped, limit it to i_size.
- Fix for build problem with CONFIG_BLOCK=n on arm at least.
- Fix for a buffer overlow on UUID partition printing.
- Trivial removal of unused variables in dac960."
