函数名称：ask_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

函数原型：void task_clear_jobctl_pending(struct task_struct *task, unsigned long mask)

返回类型：void

参数：

类型参数名称
struct task_struct *task
unsigned longmask
339  BUG_ON(mask & ~JOBCTL_PENDING_MASK)
341  如果mask按位与JOBCTL_STOP_PENDING则mask或等于JOBCTL_STOP_CONSUME按位或JOBCTL_STOP_DEQUEUED
344  JOBCTL_*, siglock protected: 与等于mask的反
346  如果非 JOBCTL_*, siglock protected: 按位与JOBCTL_PENDING_MASK的值则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
