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
