Hi Michal(CCed),

As you saw above, I'm changing:
CONFIG_BLK_DEV_NVME to CONFIG_NVME_PCI
and 
CONFIG_BLK_DEV_NVME_SCSI to CONFIG_NVME_SCSI

Is there Kconfig magic to keep existing config working?
ie, if CONFIG_BLK_DEV_NVME was set in .config, then CONFIG_NVME_PCI
should be set automatically?

Thanks,
Ming
