    If it matters that the thread can miss wakeup events and sleep indefinitely
    while there's a 'SERIO_RESCAN' event pending, then yes it looks buggy.

    serio_thread() serio_rescan()
    -------------- --------------

    serio->event |= SERIO_RESCAN;


    If both serio_thread() and serio_rescan() hold the BKL you're OK. It looks
    like serio_rescan() doesn't, though.

    > What should be it replaced with?

    In general, the response 'anything but sleep_on' is considered appropriate.
    Try wait_event().
