I reviewed and tested the integrated four-patch series in mm-new:

a20e38846efb..72dc8fdaae62

The integrated commits had stable patch-ids matching the posted patches.
DAMON KUnit passed 42/42 tests. I also ran test-only eligible_mem_bp nid and
two-kdamond refresh-isolation regression cases; they passed 42/42 and 43/43
tests, respectively. Both test-only changes were then removed and the
worktree returned clean at the unchanged series tip.

These were functional UML KUnit tests. The fixes look good to me.

For the series:
