函数名称:ask_clear_jobctl_trapping - clear jobctl trapping bit*@task: target task* If JOBCTL_TRAPPING is set, a ptracer is waiting for us to enter TRACED.* Clear it and wake up the ptracer. Note that we don't need any further* locking

函数原型:void task_clear_jobctl_trapping(struct task_struct *task)

返回类型:void

参数:

类型参数名称
struct task_struct *task
315  如果此条件成立可能性小(为编译器优化)( JOBCTL_*, siglock protected: & JOBCTL_TRAPPING)则
316  JOBCTL_*, siglock protected: 与等于JOBCTL_TRAPPING的反
317  smp_mb()
318  wake_up_bit( & JOBCTL_*, siglock protected: , switching to TRACED )

task_clear_jobctl_pendingask_clear_jobctl_pending - clear jobctl pending bits*@task: target task*@mask: pending bits to clear* Clear @mask from @task->jobctl. @mask must be subset of* %JOBCTL_PENDING_MASK. If %JOBCTL_STOP_PENDING is being cleared, other
ptrace_stopThis 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
