    sysfs makes adding new attributes easier, yes. But once added you
    cannot remove the attribute again - ever. Which means that either way
    you need to tread carefully and think twice before making a rash

    Could be useful, I don't mind you sending a patch. However, does this
    means that MEMGETINFO64 or some other ioctl should not be done? Should
    flash_erase open, read and close 8 seperate files instead of doing a
    single ioctl? And should our support for large devices wait for the
    sysfs support that has been talked about and not done for about two
    years already?

    Call me a sceptic.
