* 'tj-block-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc:
  virtio_blk: mark virtio_blk with __refdata to kill spurious section mismatch
  block: sysfs fix mismatched queue_var_{store,show} in 64bit kernel
  ataflop: adjust NULL test
  block: fix failfast merge testing in elv_rq_merge_ok()
  z2ram: Small cleanup for z2ram.c
