[lttng-dev] [PATCH] tracepoint event exclusion

[Woegerer, Paul]

Hi,

In order to support situations where a user wants generally all 
tracepoints enabled but specific tracepoints to be suppressed during a 
trace session, I created a small patch that allows us to do the following:

...
lttng enable-event -u -c met_tools -a
lttng enable-event -u -c met_tools --tracepoint '!met_func:*'
lttng enable-event -u -c met_tools --tracepoint '!met_call:*'
...

This has the effect that all tracepoints get recorded except for 
tracepoints that match met_func:* or met_call:*.

If you think this feature is useful for others we would be happy to see 
this patch merged into trunk.

Thanks,
Paul
