Keith -

As we discussed for mpt3sas driver NVME driver support, there was request
to add linux-nvme at lists.infradead.org for NVME related discussion.
https://marc.info/?l=linux-kernel&m=149874673729467&w=2

As you mentioned, we are not touching NVME subsystem, we can skip to add
NVME mailing list for future submission w.r.t NVME drive behind MR
(megaraid_sas) and HBA (mpt3sas).
All the NVME drives behind MegaRaid controller is SCSI device irrespective
of transport.
