The patchset removes 20 lines from include/linux/*.h and removes exactly zero lines from mm/*.c. Freaky. If we were ever brave/stupid emough to make CONFIG_CGROUP_MEM_RES_CTLR=y unconditional, how much could we simplify mm/? We are adding bits of overhead to the CONFIG_CGROUP_MEM_RES_CTLR=n case all over the place. This patchset actually decreases the size of allnoconfig mm/built-in.o by 1/700th. A "struct mem_cgroup" sometimes gets called "mem", sometimes "memcg", sometimes "mem_cont". Any more candidates? Is there any logic to this? Anyway... it all looks pretty sensible to me, but the timing (at -rc8!) is terrible.
