subsystem name is optional, but it is displayed in the available_events
file. All of the events in a subsystem can be specified via the syntax

+ ``<match>*``
will match functions that begin with <match>

+ ``*<match>``
will match functions that end with <match>

will match functions that begin with <match1> and end with <match2>
