Subject: [GIT PULL] Block changes for 3.16-rc

Hi Linus,

A small collection of fixes/changes for the current series. The pull
request contains:

- Removal of dead code from Gu Zheng.

- Revert of two bad fixes that went in earlier in this round, marking
  things as __init that were not purely used from init.

- A fix for blk_mq_start_hw_queue() using the __blk_mq_run_hw_queue(),
  which could place us wrongly. Make it use the non __ variant, which
  handles cases where we are called from the wrong CPU set. From me.

- A fix for drbd, which allocates discard requests without room for the
  SCSI payload. From Lars Ellenberg.

- A fix for user-after-free in the blkcg code from Tejun.

- Addition of limiting gaps in SG lists, if the hardware needs it. This
  is the last pre-req patch for blk-mq to enable the full NVMe
  conversion. Could wait until 3.17, but it's simple enough so would be
  nice to have everything we need for the NVMe port in the 3.17 release.
  From me.


Please pull!
