Hi,

This is the test result on linux 5.7.17/5.8.18/5.9.16 with
CONFIG_DEBUG_VM=y and
CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y,
but without the debug patch from Yang Shi 

linux 5.7.17: this problem yet not happan after 6 tests.

linux 5.8.18: this problem yet not happan after 6 tests.

linux 5.19.16: this problem yet not happen ater 5 tests,
	but triggered a new problem, see dmesg-5.9.16.txt

we also noticed that the btrfs filesystem performance improvement in
5.10.x, that maybe change the memory reclaim frequency too.

Best Regards
