rtla osnoise and timerlat are causing a segmentation fault when running
with the --trace option on a kernel that does not support multiple
instances. For example:
[root@f34 rtla]# rtla osnoise top -t
failed to enable the tracer osnoise
Could not enable osnoiser tracer for tracing
Failed to enable the trace instance
Segmentation fault (core dumped)
This error happens because the exit code of the tools is trying
to destroy the trace instance that failed to be created.
Make osnoise_destroy_tool() aware of possible NULL osnoise_tool *,
and do not attempt to destroy it. This also simplifies the exit code.
