    Hmm, OK.

    It's not configured into the kernels of either of the distros I use (Red
    Hat or SUSE). I can't have a required part of my driver depend on a
    feature that's not enabled in the major distro kernels.

    I'd like a mechanism that is (a) always there (b) easy for kernel to use
    and (c) easy for userspace to use. A sysfs file satisfies a, b, and c,
    but I can't use it; a sysfs bin file satisfies all three (a bit worse on
    b), but I can't use it; debugfs isn't there, so I can't use it.

    That leaves me with few options, I think. What do you suggest? (Please
    don't say netlink.)
