I'm not sure when some of these changes were backported, but the
unmodified lttng-modules compiles vs. 5.14.0-162.23.1

This disables the kmem and compaction modules.  I don't believe getting
these to compile will be easy, as the required struct declarations are
in vmlinux.h, and haven't been moved into mm/internal.h and mm/slab.h in
the RHEL sources.

Hi Martin,

I tested your patch and did some minor fixes, I added the base kernel version to the RHEL ABI version check in the Kbuild file because the ABI is tied to a specific kernel version and it would conflict with other RHEL versions. I also adjusted the range for 'kfree_skb' to build on RHEL9.2 kernels.

I uploaded the updated patch [1] to our gerrit instance for easier tracking on our side. Can you please test this version on your system?

You can get the patch using these commands:

  git fetch https://review.lttng.org/lttng-modules refs/changes/50/11750/3
  git cherry-pick FETCH_HEAD


Thanks,

Michael
