[ltt-dev] LTTng internals document

[Mathieu Desnoyers]

Which version of LTTng is it based on ?

Have you made sure you follow the compatibility list on
http://ltt.polymtl.ca ?

Given the APIs are not casted in stone and will likely change with
integration to the Linux kernel, the comments at the beginning of the
patches is probably the best reference. Also, going through the papers
found on the website will give you an idea of the overall design.
