Hi,
Is it possible to build the lttng modules againt Centos Stream 9
kernels? I see these warnings at the top when attempting to compile:
make[1]: Entering directory '/usr/src/kernels/5.14.0-452.el9.x86_64'

The message reads to use the full kernel source tree if you want to
enable those probes.
Those probes depend on internal headers, which are not shipped as part
of the public header packages e.g. kernel-headers.rpm.
One way to get the full source tree is to extract it from the kernel
source rpm, e.g.
https://mirror.stream.centos.org/9-stream/BaseOS/source/tree/Packages/kernel-5.14.0-452.el9.src.rpm
thanks,

I tried with module versions 2.12.17 and 2.13.13 against the kernel
5.14.0-452.el9.x86_64 and I obtain this error:
/home/tmp/git/lttng-modules/src/probes/../../include/lttng/tracepoint-event-impl.h:133:6:
error: conflicting types for 'trace_sched_stat_runtime'; have 'void(struct
task_struct *, u64, u64)' {aka 'void(struct task_struct *, long long unsigned
int, long long unsigned int)'}
Any help would be greatly appreciated.
