we have many testcases you can refer to as an example.
Your cover-letter mentions that you have tested this code, just move
all the testcases to the blktests.

More importantly for a feature like this you should be providing
outstanding testcases in your github tree when you post the
series, it should cover critical parts of the block layer and
drivers in question.

The objective here is to have blktests updated when the code
is upstream so all the distros can test the code from
upstream blktest repo. You can refer to what we have done it
for NVMeOF in-band authentication (Thanks to Hannes and Sagi
in linux-nvme email-archives.
