Subject: [GIT PULL] SCSI fixes for 4.11-rc2
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. A long
standing bug in storvsc, which recent block changes turned from being a
harmless annoyance into a hang and yet more fallout (in mpt3sas) from
the changes to device blocking. The remainder are small fixes and
updates.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
