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

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
