Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Browse source 
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."

* 'for-linus' of git://git.kernel.dk/linux-block:
  block: fix buffer overflow when printing partition UUIDs
  Fix blkdev.h build errors when BLOCK=n
  bio allocation failure due to bio_get_nr_vecs()
  block: don't mark buffers beyond end of disk as mapped
  mtip32xx: release the semaphore on an error path
  dac960: Remove unused variables from DAC960_CreateProcEntries()
