Description
Right now, once a filter is attached to an event you can't later get lttng list to tell you what the filter is.
$ lttng enable-event -u -c ch0 sample:ev* --filter "intfield < 500"
Filter 'intfield < 500' successfully set
$ lttng list z
Tracing session z: [inactive]
[...]
Events:
sample:ev* (type: tracepoint) [enabled] [with filter]
It should be a simple matter to change the list display to this:
$ lttng list z
Tracing session z: [inactive]
[...]
Events:
sample:ev* (type: tracepoint) [enabled] [with filter 'intfield < 500']
