SubjectRe: [PATCH V2] nommu: add anonymous page memcg accounting

It's reasonable to ask that features be tested every so often, and since the memory cgroup code seems to be
changing relatively frequently it probably needs exercising more often. I can't commit to this, though - I
don't know how much longer I'll be working with NOMMU kernels, and they are notoriously fragile. Any memory
access bug that would cause an oops (or SEGV) in a "normal" kernel can cause subtle and almost impossible to
debug behavior on a NOMMU system. For this reason I always try to work with "stable" kernels (recent threads
debating the term notwithstanding)...so it would be a pretty far jump to a -rc1 kernel.

Is this a showstopper (in which case David's patch to make the CGROUP_MEM_RES_CTLR Kconfig option depend on MMU
should be implemented), or should I post V3 of the patch that has Balbir's suggested change?

Steve
