Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: smarpqi, lpfc, qedi,
  megaraid_sas, libsas, zfcp, mpt3sas, hisi_sas.

  Additionally, we have a pile of annotation, unused variable and minor
  updates.

  The big API change is the updates for Christoph's DMA rework which
  include removing the DISABLE_CLUSTERING flag.

  And finally there are a couple of target tree updates"

- * Per-target queue state.
- *
- * This struct holds the data needed by the queue steering policy.  When a
- * target is sent multiple requests, we need to drive them to the same queue so
- * that FIFO processing order is kept.  However, if a target was idle, we can
- * choose a queue arbitrarily.  In this case the queue is chosen according to
- * the current VCPU, so the driver expects the number of request queues to be
- * equal to the number of VCPUs.  This makes it easy and fast to select the
- * queue, and also lets the driver optimize the IRQ affinity for the virtqueues
- * (each virtqueue's affinity is set to the CPU that "owns" the queue).
- *
- * tgt_seq is held to serialize reading and writing req_vq.
- *
- * Decrements of reqs are never concurrent with writes of req_vq: before the
- * decrement reqs will be != 0; after the decrement the virtqueue completion
- * routine will not use the req_vq so it can be changed by a new request.
- * Thus they can happen outside the tgt_seq, provided of course we make reqs
- * an atomic_t.
