from our tests, this patch has little impact.

it was applied as below ac6a9444dec85:

ac6a9444dec85 (linux-devel/fixup-c5f50d8b23c79) memcg: move stats_updates to struct mem_cgroup
c5f50d8b23c79 (linux-review/Yosry-Ahmed/mm-memcg-change-flush_next_time-to-flush_last_time/20231010-112257) mm: memcg: restore subtree stats flushing
ac8a48ba9e1ca mm: workingset: move the stats flush into workingset_test_recent()
51d74c18a9c61 mm: memcg: make stats flushing threshold per-memcg
130617edc1cd1 mm: memcg: move vmstats structs definition above flushing code
26d0ee342efc6 mm: memcg: change flush_next_time to flush_last_time
25478183883e6 Merge branch 'mm-nonmm-unstable' into mm-everything

for the first regression reported in original report, data are very close
for 51d74c18a9c61, c5f50d8b23c79 (patch-set tip, parent of ac6a9444dec85),
and ac6a9444dec85.
