[lttng-dev] [LTTNG-UST PATCH 00/01] Added event exclusion

[Ikaheimonen, JP]

This patch adds the possibility to NOT enable given events, even if they are covered by some wildcard specification.
When an event specification in the enable-event command starts with a '!' character, the specification is taken to tell which events should never be enabled.

Thus, the commands

lttng event-enable -u -s test -c testc "!ab*"
lttng event-enable -u -s test -c testc "a*"

will enable all events that begin with 'a', unless they begin with 'ab'.

On a related LTTng-tools patch, a new option --exclude (or -x) is added to the event-enable command.
This option just prepends the '!' character to the given event, and ignores all loglevel and filter options.
This, you can say
lttng event-enable -u -s test -c testc "a*" --exclude "ab*"
on one single command line.
