    That's a bit irritating, really. It means that userspace needs to be
    different for NUMA kernels (or more different, which is still bad). Boot
    into a non-NUMA kernel and whoops, no tmpfs and quite possibly no boot.

    But last time I whined about this Albert had a list of fairly
    reasonable-sounding reasons why filesystems shouldn't silently accept
    not-understood options.

    But in this case, we _do_ understand them. We're just not going to do
    anything about them.

    I just wonder if we're being as friendly as we possibly can be to admins
    and distro-makers.

    [ Vaguely suprised that tmpfs isn't using match_token()... ]
