       void task_clear_jobctl_trapping(struct task_struct * task);

ARGUMENTS
       task
           target task

DESCRIPTION
       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.  task->siglock guarantees
       that task->parent points to the ptracer.
