Subject: NVME M2 devices on RAID configured controllers

More and more system are coming with M2 devices on RAID configured
controllers which Linux does not support.  Switching to AHCI mode
instead of RAID mode allows it to see the drives but that is not a fix
when you want it in RAID mode and want to use Windows as well.   The
question I have is this being worked on?   If not, why isn't it
finding the NVME devices on a controller configured as RAID (Is there
a new PCI class code?)?

In general, MDAdm shouldn't be looking for firmware RAID when the PCI
class isn't in RAID mode, but that's a whole other issue.

Thanks.
