       The mm and pcmcia ones look particularly interesting.

    For the mm/vmscan.c one, the "fix" is wrong.
    If "result" is ever non-zero, the functions called
    have dropped the lock already. See "try_to_swap_out" which is the
    only place from non-zero return values can originate in these paths.
