函数名称：complete_signal

函数原型：static void complete_signal(int sig, struct task_struct *p, enum pid_type type)

返回类型：void

参数：

类型参数名称
intsig
struct task_struct *p
enum pid_typetype
986  signal等于信号
995  如果Test if P wants to take SIG. After we've checked all threads with this,* it's equivalent to finding no threads not blocking SIG. Any threads not* blocking SIG were ruled out because they are not running and already* have pending signals则t等于p
997  否则如果type恒等于单一进程或thread_group_empty(p)则返回
1003  否则
1007  t等于current thread group signal load-balancing target:
1008  当非Test if P wants to take SIG. After we've checked all threads with this,* it's equivalent to finding no threads not blocking SIG. Any threads not* blocking SIG were ruled out because they are not running and already* have pending signals循环
1009  t等于next_thread(t)
1010  如果t恒等于current thread group signal load-balancing target: 则返回
1018  current thread group signal load-balancing target: 等于t
1025  如果sig_fatal(p, sig)且非see SIGNAL_* flags below 按位与group exit in progress 的值且非sigismember( & real_blocked, sig)且sig恒等于SIGKILL或非ptrace的值则
1032  如果非sig_kernel_coredump(sig)则
1039  see SIGNAL_* flags below 等于group exit in progress
1040  hread group exit support 等于sig
1041  hread group stop support, overloads group_exit_code too 等于0
1042  t等于p
