There has been a lot of changes in the last few cycles. You can find the latest version on the "next" branch of the kselftest repo [1] where most recent enhancements are queued up for inclusion. If you are interested, there is one more series [2] pending merge to the kselftest repo, it adds a new test for the recent non-contiguous CBM support.
