I honestly don't know why both LTP and kselftests exist. But I *did*
specifically ask about LTP and got a "yes" from both you and Greg.

I suppose I can go back and remove all the LTP niceties that I just
added to my bare script (setup, cleanup, clean handling of individual
test cases, unified reporting stats; does selftests have any of
that?)... But that'll have to be next week, if I can find the time at
all.

Since the tests cases are so similar, my current script tests both
debugfs and tracefs. So I probably won't create two separate buckets for
this.
