int tracehook_notify_jctl ( | int notify, |
int why); |
notifynonzero if this is the last thread in the group to stop
why
CLD_STOPPED or CLD_CONTINUED
This is called when we might call do_notify_parent_cldstop.
It's called when about to stop for job control; we are already in
TASK_STOPPED state, about to call schedule. It's also called when
a delayed CLD_STOPPED or CLD_CONTINUED report is ready to be made.
Return nonzero to generate a SIGCHLD with why, which is
normal if notify is nonzero.
Called with no locks held.
