Name:ask_set_jobctl_pending - set jobctl pending bits*@task: target task*@mask: pending bits to set* Clear @mask from @task->jobctl. @mask must be subset of* %JOBCTL_PENDING_MASK | %JOBCTL_STOP_CONSUME | %JOBCTL_STOP_SIGMASK |* %JOBCTL_TRAPPING
Proto:bool task_set_jobctl_pending(struct task_struct *task, unsigned long mask)
Type:bool
Parameter:
Type | Parameter | Name |
---|---|---|
struct task_struct * | task | |
unsigned long | mask |
287 | BUG_ON(mask & ~(JOBCTL_PENDING_MASK | JOBCTL_STOP_CONSUME | signr of the last group stop | JOBCTL_TRAPPING)) |
289 | BUG_ON((mask & JOBCTL_TRAPPING) && !(mask & JOBCTL_PENDING_MASK)) |
291 | If Value for the false possibility is greater at compile time(fatal_signal_pending(task) || ( Per task flags (PF_*), defined further below: & Getting shut down )) Then Return false |
294 | If mask & signr of the last group stop Then siglock protected &= ~signr of the last group stop |
297 | siglock protected |= mask |
298 | Return true |

ptrace_trap_notify | ptrace_trap_notify - schedule trap to notify ptracer*@t: tracee wanting to notify tracer* This function schedules sticky ptrace trap which is cleared on the next* TRAP_STOP to notify ptracer of an event. @t must have been seized by* ptracer. |
do_signal_stop | do_signal_stop - handle group stop for SIGSTOP and other stop signals*@signr: signr causing group stop if initiating* If %JOBCTL_STOP_PENDING is not set yet, initiate group stop with @signr* and participate in it |
ptrace_init_task | ptrace_init_task - initialize ptrace state for a new child*@child: new child task*@ptrace: true if child should be ptrace'd by parent's tracer* This is called immediately after adding @child to its parent's children* list |
