Hi,
I'm working on libtraceevent and libtracefs update. There will be soname bump happening to them. Namely,
libtraceevent.so 1.6.3 -> 1.7.2 libtracefs.so 1.5.0 -> 1.6.4
IIRC only kernel-tools (for perf and rtla) and trace-cmd depends on them. So I'm also copying their corresponding contacts.
As for libtraceevent, I've tried running trace-cmd/perf/rtla with the new version and they still works. So I've updated it in Rawhide, Fedora 38 and Fedora 37. They are now in Bodhi.
As for libtracefs I've built it in side tag f39-build-side-65890. I plan to update it in both Rawhide and Fedora 38 this week.
HTH.
