Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"First round of SCSI updates for the 4.6+ merge window.
This batch includes the usual quota of driver updates (bnx2fc, mp3sas,
hpsa, ncr5380, lpfc, hisi_sas, snic, aacraid, megaraid_sas). There's
also a multiqueue update for scsi_debug, assorted bug fixes and a few
other minor updates (refactor of scsi_sg_pools into generic code, alua
and VPD updates, and struct timeval conversions)"
* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (138 commits)
