trace_signal_generate - called when a signal is generated
void trace_signal_generate(int sig, struct siginfo * info, struct task_struct * task, int group, int result);
Current process sends a 'sig' signal to 'task' process with 'info' siginfo. If 'info' is SEND_SIG_NOINFO or SEND_SIG_PRIV, 'info' is not a pointer and you can't access its field. Instead, SEND_SIG_NOINFO means that si_code is SI_USER, and SEND_SIG_PRIV means that si_code is SI_KERNEL.
