    defintily not on sysfs. sysfs doesn't allow drivers to modify the
    file operations for good reasons. it'll probably work the same as-is
    when you use the rely file operations on debugfs or a custom filesystem,
    although you're code will have zero chance to get merged when it modifies
    an existing file operations struct or adds an ioctl.
