    Fair enough.

    We should be pretty careful about what we put in meminfo - it's the
    top-level, most-important procfs file and I expect that quite a lot of
    userspace reads it with some frequency. We don't want to clutter it
    up. /proc/vmstat is a suitable place for the less important info which
    is more kernel developer oriented.

    But CMATotal and CMAFree do pass the "should be in meminfo" test, IMO.
