How to build lttng on RHEL 9?

[David Aldrich]

Hi Kienan

I have updated to the latest kernel version for RHEL 9.6, which is:

5.14.0-611.24.1.el9_7.x86_64

AI suggests 'RHEL 9.7 backported into its 5.14.z stream: dev_base_lock
was removed from the networking core' which I guess causes the
problem?

Is it possible to provide a fix for this?

Best regards
David
