I still wish it's folded into CONFIG_MEMCG and conditionalized just on
CONFIG_SWAP tho.

In old days, memsw controller was not very stable. So, we devided the
config.
And, it makes size of memory for swap-device double (adds 2bytes per
swapent.)
That is the problem.

That's the tendency to happen with anything new, since we want to add it
without disrupting what's already in there. I am not very fond of config
options explosions myself, so I am for removing it.
