the regression is partially recovered by applying your patch.
(but one even more regression case as below)
details:
since you mentioned the whole patch-set behavior last time, I applied the
patch upon
a94032b35e5f9 memcg: use proper type for mod_memcg_state
below fd2296741e2686ed6ecd05187e4 = a94032b35e5f9 + patch
for the regression in our original report, test machine is:
model: Skylake
nr_node: 2
nr_cpu: 104
memory: 192G
regression partially recovered:
