Documentation/trace: Add clarification how histogram onmatch works

2019-05-08T20:32:05Z

The current trace documentation, the section describing histogram's "onmatch" is not straightforward enough about how this action is applied. It is not clear what criteria are used to "match" both events. A short note is added, describing what exactly is compared in order to match the events.

tracing: Add alternative synthetic event trace action syntax

2019-02-20T18:51:07Z

Add a 'trace(synthetic_event_name, params)' alternative to synthetic_event_name(params). Currently, the syntax used for generating synthetic events is to invoke synthetic_event_name(params) i.e. use the synthetic event name as a function call. Users requested a new form that more explicitly shows that the synthetic event is in effect being traced. In this version, a new 'trace()' keyword is used, and the synthetic event name is passed in as the first argument. In addition, for the sake of consistency with other actions, change the documention to emphasize the trace() form over the function-call form, which remains documented as equivalent.

The action/handler code refactoring didn't change the action/handler syntax, but did generalize it - the Documentation should reflect that.
