Merge git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target fixes from Nicholas Bellinger:
"The bulk of the series are bugfixes for qla2xxx target NPIV support
that went in for v3.14-rc1. Also included are a few DIF related
fixes, a qla2xxx fix (Cc'ed to stable) from Greg W., and vhost/scsi
protocol version related fix from Venkatesh.
Also just a heads up that a series to address a number of issues with
iser-target active I/O reset/shutdown is still being tested, and will
be included in a separate -rc6 PULL request"
