返回类型：void

参数：无

signal等于signal

2420

signr等于jobctl按位与signr of the last group stop

2422

如果ptrace按位与SEIZE used, enable new behavior 则

2423

如果非hread group stop support, overloads group_exit_code too 且非see SIGNAL_* flags below 按位与job control stop in effect 的值则signr等于SIGTRAP

2426

WARN_ON_ONCE(!signr)

2427

ptrace_do_notify(signr, signr | (Extended result codes which enabled by means other than options. << 8), child has stopped )

2429

否则

2430

WARN_ON_ONCE(!signr)

2431

This must be called with current->sighand->siglock held.* This should be the path for all ptrace stops.* We always set current->last_siginfo while stopped here.* That makes it a way to test a stopped process for
