[lttng-dev] [PATCH lttng-tools 00/28] UST Event exclusions

[JP Ikaheimonen]

This patch set, along with a patch set for lttng-ust, implements
a new option for lttng enable-event command.

The new option makes it possible to exclude events from a wildcarded
event definition.

That is, running command

lttng enable-event -u -c c1 'myevents*' -x 'myevents:dbg*'

would enable all UST tracepoint events whose names start with 'myevents'
except those that start with 'myevents:dbg'.

The lttng list command is also updated, so that it points out the
fact that an event has some exclusions.
