Commit 5bbc2b785e63 ("selftests/mm: fix FORCE_READ to read input
value correctly") modified FORCE_READ() to take a value instead of a
pointer. It also changed most of the call sites accordingly, but
missed many of them in cow.c. In those cases, we ended up with the
pointer itself being read, not the memory it points to.
No failure occurred as a result, so it looks like the tests work
just fine without faulting in. However, the huge_zeropage tests
explicitly check that pages are populated, so those became skipped.
Right, that's nasty! Thanks!
For all cases, we could probably just fail if the memory is not
populated after FORCE_READ().
Would you have time to prepare a patch for that?
