Merge tag 'trace-tools-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull trace tool updates from Steven Rostedt:
"Tracing:
- Update makefiles for latency-collector and RTLA, using tools/build/
makefiles like perf does, inheriting its benefits. For example,
having a proper way to handle library dependencies.
- The timerlat tracer has an interface for any tool to use. rtla
timerlat tool uses this interface dispatching its own threads as
workload. But, rtla timerlat could also be used for any other
process. So, add 'rtla timerlat -U' option, allowing the timerlat
tool to measure the latency of any task using the timerlat tracer
interface.
Verification:
- Update makefiles for verification/rv, using tools/build/ makefiles
like perf does, inheriting its benefits. For example, having a
proper way to handle dependencies"
