I'd ask that you put a limit on the number of memcgs you print statistics
for to prevent spamming the kernel log, otherwise it would be trivial to
overwrite the entire buffer.  Do we really need the memory statistics forank
the memcg 32 levels above us, for example?

Yeah, now there is no limit on numbers of printed memcg. But do we really
need to build so complicate memcg hierarchy for 32 levels? There is no
such usage now at least in our environment. : )


Thanks,
