NAME

tracehook_notify_jctl - report about job control stop/continue

SYNOPSIS

int tracehook_notify_jctl(int notify, int why);

ARGUMENTS

notify

zero, CLD_STOPPED or CLD_CONTINUED

why


CLD_STOPPED or CLD_CONTINUED

DESCRIPTION

This is called when we might call do_notify_parent_cldstop.

notify is zero if we would not ordinarily send a SIGCHLD, or is the CLD_STOPPED or CLD_CONTINUED .si_code for SIGCHLD.

why is CLD_STOPPED when about to stop for job control; we are already in TASK_STOPPED state, about to call schedule. It might also be that we have just exited (check PF_EXITING), but need to report that a group-wide stop is complete.

why is CLD_CONTINUED when waking up after job control stop and ready to make a delayed notify report.

Return the CLD_* value for SIGCHLD, or zero to generate no signal.

Called with the siglock held.
