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)"

A value of zero + means the feature is disabled and the controller may not use + the direct i/o path to physical devices.
