To make thp test simple, maybe just add one more test to MOVE a large chunk to replace the thp test, which may contain a few thps? It also doesn't need to be fault based.
Sorry, I didn't get your suggestion. Could you please clarify? Which thp test are you referring to?
The new "move-pmd" test.
I meant maybe it makes sense to have one separate MOVE test for when one ioctl(MOVE) covers a large range which can cover some thps. Then that will trigger thp paths. Assuming the fault paths are already covered in the generic "move" test.
Thanks,
