Subject: [GIT PULL] Block fixes for 3.17

Hi Linus,

Smaller collection of fixes that have come up since the initial merge
window pull request. It contains:

- Error handling cleanup and support for larger than 16 byte cdbs in
  sg_io() from Christoph. The latter just matches what bsg and friends
  support, sg_io() got left out in the merge.

- An option for brd to expose partitions in /proc/partitions. They are
  hidden by default for compat reasons. From Dmitry Monakhov.

- A few blk-mq fixes from me - killing a dead/unused flag, fix for
  merging happening even if turned off, and correction of a few
  comments.

- Removal of unnecessary ->owner setting in systemace. From Michal
  Simek.

- Two related fixes for a problem with nesting freezing of queues in
  blk-mq. One from Ming Lei removing an unecessary freeze operation, and
  another from Tejun fixing the nesting regression introduced in the
  merge window.

- Fix for a BUG_ON() at bio_endio time when protection info is attached
  and the IO has an error. From Sagi Grimberg.

- Two scsi_ioctl bug fixes for regressions with scsi-mq from Tony
  Battersby.

- A cfq weight update fix and subsequent comment update from Toshiaki
  Makita.


Please pull!
