Thank you for this report! I sent a fix: https://lore.kernel.org/linux-mm/20211014110848.5204-1-sj@xxxxxxxxxx/ This was found and fixed by Andrew before, but I made this mistake again... :'( To not repeat this again, I added a test for this case in DAMON correctness tests: https://github.com/awslabs/damon-tests/commit/b3d1513ad16a Thanks, SJ > > -- > ~Randy
