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

Pull first round of SCSI updates from James Bottomley:
 "This patch consists of the usual driver updates (megaraid_sas,
  scsi_debug, qla2xxx, qla4xxx, lpfc, bnx2fc, be2iscsi, hpsa, ipr) plus
  an assortment of minor fixes and the first precursors of SCSI-MQ (the
  code path simplifications) and the bug fix for the USB oops on remove
  (which involves an infrastructure change, so is sent via the main tree
  with a delayed backport after a cycle in which it is shown to
  introduce no new bugs)"

+Description:    This file contains the current status of the "SSD Smart Path"
+                feature of HP Smart Array RAID controllers using the hpsa
+                driver.  SSD Smart Path, when enabled permits the driver to
+                send i/o requests directly to physical devices that are part
+                of a logical drive, bypassing the controllers firmware RAID
+                stack for a performance advantage when possible.  A value of
+                '1' indicates the feature is enabled, and the controller may
+                use the direct i/o path to physical devices.  A value of zero
+                means the feature is disabled and the controller may not use
+                the direct i/o path to physical devices.  This setting is
+                controller wide, affecting all configured logical drives on the
+                controller.  This file is readable and writable.
