Someone (sorry, can't find the old mail) pointed out last time that the 'pid_t *__user tidptr' argument needs to be an independent pointer, in order to allow the same use patterns with CLONE_CHILD_SETTID and CLONE_CHILD_CLEARTID that you can do with the current clone implementation. Moving that argument from clone_struct into the argument list would also make this a three-argument syscall, which solves the naming problem.
