  cfq: explicitly use 64bit divide operation for 64bit arguments (2013-09-22 12:43:47 -0600)

Anatol Pomozov (1):
      cfq: explicitly use 64bit divide operation for 64bit arguments

Bjorn Helgaas (1):
      bio-integrity: Fix use of bs->bio_integrity_pool after free

Jianpeng Ma (1):
      block: trace all devices plug operation

Joe Perches (1):
      block: Convert kmalloc_node(...GFP_ZERO...) to kzalloc_node(...)

Jun'ichi Nomura (1):
      block: Add nr_bios to block_rq_remap tracepoint

Mike Christie (1):
      If the queue is dying then we only call the rq->end_io callout.     This leaves bios setup on the request, because the caller assumes when     the blk_execute_rq_nowait/blk_execute_rq call has completed that     the rq->bios have been cleaned up.

Tejun Heo (1):
      blkcg: relocate root_blkg setting and clearing
