LTTng and SystemTAP

Hi Tom,

I cannot find in which email you proposed it, but it would be very interesting
to have SystemTAP outputting its buffers to LTTng. It should be quite
straightforward :

1 - Create a new XML facility (systemtap), with an event (log) in it, which
would take a sequence of char or a simple string as parameter.

2 - run genevent to create the facility, copy it into the LTTng patched kernel.

3 - Adapt Systemtap to use the generated inline function to send its data out
instead of directly using relayfs.

If anyone has time to try this, it would be very interesting to see the result.

Thanks,

Mathieu
