Hi PCP folks,

We've been testing NVME storage for a while now, and found that the
linux pmda was not recognizing the difference between a device and a
partition for NVME devices.   The NVME devices were missing from
disk.dev, but both the disks and partitions would show up under
disk.partitions.

Since I can hardly write hello.c anymore, Suruchi Kadu, one of my
teammates wrote this patch to try to add nvme devices to disk.dev. Seems
to work for us.   Can you either add this patch, or something
functionally equivalent?

Thanks Doug and Suruchi.

Patch look fine to me, I'll merge into my tree and push upstream from there.

Here's a little tutorial about NVME device naming just in case you don't
have any yet.

No I don't have one, but I have a spare slot if Intel would like to make a donation ... 8^)>

Cheers and thanks, Ken.
