    Well ... the comment was there, but the problem with comments
    is no one reads them ;)

    Agreed. I'm still scratching my head coming up with a better way.

    Hmmm ... except for the call from fork, all calls to this are from
    within mm/mempolicy.c. I could make the routine within mempolicy.c
    static, and provide an exported wrapper with a name like:


    that wrapped it. With a name like that, there seems less risk of
    abusing this.

    Any other suggestions?

    I won't rest till it's the best ...
