task_clear_jobctl_pending - clear jobctl pending bits : target task : pending bits to clear
Clear from ->jobctl. must be subset of JOBCTL_PENDING_MASK. If JOBCTL_STOP_PENDING is being cleared, other STOP bits are cleared together.
If clearing of leaves no stop or trap pending, this function calls task_clear_jobctl_trapping().
CONTEXT: Must be called with ->sighand->siglock held.
Definition at line 295 of file signal.c.
task_clear_jobctl_trapping - clear jobctl trapping bit : 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. ->siglock guarantees that ->parent points to the ptracer.
CONTEXT: Must be called with ->sighand->siglock held.

task_set_jobctl_pending - set jobctl pending bits : target task : pending bits to set
Clear from ->jobctl. must be subset of JOBCTL_PENDING_MASK | JOBCTL_STOP_CONSUME | JOBCTL_STOP_SIGMASK | JOBCTL_TRAPPING. If stop signo is being set, the existing signo is cleared. If is already being killed or exiting, this function becomes noop.
CONTEXT: Must be called with ->sighand->siglock held.
RETURNS: true if is set, false if made noop because was dying.
