[Jens Axboe]

Hi Linus,

4 small fixes that should be merged for the current 3.18-rc series. This
pull request contains:

- A minor bugfix for computation of best IO priority given two merging
  requests. From Jan Kara.

- The final (final) merge count issue that has been plaguing virtio-blk.
  From Ming Lei.

- Enable parallel reinit notify for blk-mq queues, to combine the cost
  of an RCU grace period across lots of devices. From Tejun Heo.

- An error handling fix for the SCSI_IOCTL_SEND_COMMAND ioctl. From Tony
  Battersby.

Please pull!
