If you want to work on adding support within lttng-modules and lttng-tools to enable tracing of userspace through uprobes, it would certainly be welcome! > > I did some research on buffer management of LTTng.

One main thing I want us to be careful about: if we do that, we need some kind of versioning information in the tracer that can be checked by the core dumper, so we can do changes internally without breaking the code dump.
