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
