Moving these tests into the nvme directory is possible but will make it
harder to run the NVMeOF multipath tests separately. Are you fine with this?

Both way's have it's up and downsides, I agree.

Having two distinct groups requires to run './check nvme nvmeof-mp' to
run full coverage with nvme.

Having it all in one group would require to run './check nvme 18 19 20
21 22 23 24 ...' to get only the dm-mpath ones.

Honestly I hate both but your's (the two distinct groups) is probably
easier to handle in the end, I have to admit.

Omar, do you have a preference for one of the two aforementioned approaches?

Let's keep it in a separate category, since lots of people running nvme
tests probably aren't interested in testing multipath.

A bunch of the tests failed with

modprobe: FATAL: Module nvme is in use.

Maybe related to my test VM having an nvme device?

Hello Omar,

Can you have a look at the updated master branch of https://github.com/bvanassche/blktests? That code should no longer fail if unloading the nvme kernel module fails. Please note that you will need kernel v4.18 to test these scripts - a KASAN complaint appears if I run these tests against kernel v4.19-rc4.

Thanks,

Bart.
