DESCRIPTION
This family of probe points is used to probe signal activities.
Since there are so many signals sent to processes at any given
point, it is advisable to filter the information according to the
requirements. For example, filter only for a particular signal
(if sig==2) or for a particular process (if pid_name==stap).
