Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley:
"This is a rather large set of fixes. The bulk are for lpfc correcting
a lot of issues in the new NVME driver code which just went in in the
merge window.
The others are:
- fix a hang in the vmware paravirt driver caused by incorrect
handling of the new MSI vector allocation
- long standing bug in storvsc, which recent block changes turned
from being a harmless annoyance into a hang
- yet more fallout (in mpt3sas) from the changes to device blocking
The remainder are small fixes and updates"
