Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "Mainly sending this off now for the writeback fixes, since they fix a
  real regression introduced with the cgroup writeback changes.  The
  NVMe fix could wait for next pull for this series, but it's simple
  enough that we might as well include it.

  This contains:

   - two cgroup writeback fixes from Tejun, fixing a user reported issue
     with luks crypt devices hanging when being closed.

   - NVMe error cleanup fix from Jon Derrick, fixing a case where we'd
     attempt to free an unregistered IRQ"
