-* Workflow for updating patches from newer kernel:
-
-Pull the new headers from mainline kernel to lttng-modules/.
-Update those headers to fix the lttng-modules instrumentation style.
-
-
-* Workflow to add new Tracepoint instrumentation to newer kernel,
- and add support for it into LTTng:
-
-a) instrument the kernel with new trace events headers. If you want that
- instrumentation distributed, you will have to push those changes into
- the upstream Linux kernel first,
-b) copy those headers into lttng-modules/ directory,
-c) look at a diff from other headers between mainline kernel version and
- lttng-modules/, and use that as a recipe to alter the new
- lttng-modules/ headers.
-d) create a new file in probes/ for the new trace event header you added,
-e) add it to probes/Makefile,
-f) build, make modules_install,
-g) don't forget to load that new module too.
-
-Currently, LTTng policy is to only accept headers derived from trace
-event headers accepted into the Linux kernel upstream for tracepoints
-related to upstream kernel instrumentation.
