名称描述
do_group_exitTake down every thread in the group. This is called by fatal signals* as well as by sys_exit_group (below).
de_threadThis function makes sure the current process has its own signal table,* so that flush_signal_handlers can later reset the handlers without* disturbing other processes. (Other processes might share the signal* table via the CLONE_SIGHAND option to clone().)
