OK, and Mark Brown's nearby response [1] supports that, as well.

Thus fortified, I plan on doing the following steps:

Step 1: Do nothing about the revert patch that I sent earlier, thus
allowing it to continue in its journey (so far, Andrew has moved it into
mm-hotfixes-stable branch).

Step 2: Send out a patch for a modest part of selftests/mm, that uses
this latest approach, and see how it fares in reviews.
