Linus,

[
  Note, the biggest change here is the restructuring of the Makefiles to
  warn about missing libraries that you asked us to do last merge window.
  It follows perf in which you don't have the libraries, you now get:

  Auto-detecting system features:
  ...                           libtraceevent: [ OFF ]
  ...                              libtracefs: [ OFF ]

  libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel
  libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
]

Updates to tools/tracing and verification for 6.9:

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.

Daniel Bristot de Oliveira (4):
      tools/tracing: Use tools/build makefiles on latency-collector
      tools/rtla: Use tools/build makefiles to build rtla
      tools/verification: Use tools/build makefiles on rv
      tools/rtla: Add -U/--user-load option to timerlat
