[PATCH] lpfc: Finalize Kconfig options for nvme

From: James Smart Reviewing the result of what was just added for Kconfig, we made a poor choice. It worked well for full kernel builds, but not so much for how it would be deployed on a distro. Here's the final result: - lpfc will compile in NVME initiator and/or NVME

[PATCH] storvsc: workaround for virtual DVD SCSI version

Hyper-V host emulation of SCSI for virtual DVD device reports SCSI version 0 (UNKNOWN) but is still capable of supporting REPORTLUN. Without this patch, a GEN2 Linux guest on Hyper-V will not boot 4.11 successfully with virtual DVD ROM device. What happens is that the SCSI scan process falls
