Subject: [PATCH 0/4] blk-mq: cleanup on all kinds of kobjects

This patchset cleans up on kojects of request_queue.mq_kobj,
sw queue's kobject and hw queue's kobject.

The 1st patch initialized kobject of request_queue and sw queue
in blk_mq_init_allocated_queue(), so we can avoid to initialize
these kobjects several times, and this patch fixes one kerne
warning reported from Omar Sandoval.

The 2nd patch makes lifetime consitent between mq request queue/sw
queue and their kobjects.

The 3rd patch makes lifetime consitent between hw queue and their
kobjects.

The last patch is a followup of 3rd patch.

Thanks,
Ming

  blk-mq: initialize mq kobjects in blk_mq_init_allocated_queue()
  blk-mq: make lifetime consitent between q/ctx and its kobject
  blk-mq: make lifetime consistent between hctx and its kobject
  blk-mq: free hctx->cpumask in release handler of hctx's kobject
