signal
SYNOPSIS
int tracehook_consider_fatal_signal(struct task_struct * task,
int sig);
ARGUMENTS
task
task receiving the signal
sig
signal number being sent
DESCRIPTION
Return nonzero to prevent special handling of this termination signal.
Normally handler for signal is SIG_DFL. It can be SIG_IGN if sig is
ignored, in which case force_sig is about to reset it to SIG_DFL. When
this returns zero, this signal might cause a quick termination that
does not give the debugger a chance to intercept the signal.
Called with or without task->sighand->siglock held.
