Agreed.
I've chucked my patches that fixed the build here as well, since they
were very similar to yours.
I'll continue creating a dummy package / distro feature option here,
since pulling those patches along is a particular pain point for me, as
I continually hit lttng issues as I work through new kernels :D

I know nothing about lttng myself, but has passed on your concerns to our
maintainer for the functionality. Unfortunately he is on vacation for a
couple of weeks more, so I do not know when I can expect an answer from
him.
So for now I hope we can update the recipe per my patches so that it
continues to work as before, and then we can take the discussion of
whether it should be possible to build lttng-modules without
CONFIG_TRACEPOINTS enabled separately.
//Peter

We really should stop dragging these patches along at all.
I have a unified set of patches here as well, but continuing to allow
lttng modules to build in configurations like these, just doesn't make
sense (which is why I haven't sent them).
We should have a distro feature, and simply drop it from package lists
when appropriate.

Right, I had missed that there were two patches doing the same thing
(though neither actually solved the problem after the update to 2.13.0).
I will send an updated review unifying the patches and adding my solution
to disable building the module when CONFIG_TRACEPOINTS is not enabled.

I guess the patch you've refreshed is not a correct one...
There is another patch introduced by Bruce in the commit 18bf7b0
("lttng-modules: update devupstream to v2.13-rc "), namely
0001-src-Kbuild-change-missing-CONFIG_TRACEPOINTS-to-warn.patch
It make sense to refresh rather that one instead of the Makefile one,
and have it included in the SRC_URI (see discussion in
https://lists.openembedded.org/g/openembedded-core/topic/84950303#154888).
