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.
