[PATCH 0/3] rtla/timerlat: Set OSNOISE_WORKLOAD for kernel threads

[Tomas Glozar]

The patchset makes both rtla-timerlat-hist and rtla-timerlat-top set
OSNOISE_WORKLOAD to the proper value ("on" when running with -k, "off"
when running with -u) every time the option is available instead of setting it
only when running with -u.

This prevents rtla timerlat -k from giving no results when
NO_OSNOISE_WORKLOAD is set, either manually or by an abnormally exited earlier
run of rtla timerlat -u.

osnoise_set_workload is made to distinguish between the option missing
altogether and it failing to be set. In the first case, rtla-timerlat will
ignore setting the option to preserve compatibility of kernel-thread mode
on older kernels without the OSNOISE_WORKLOAD option.

Tomas Glozar (3):
  rtla/osnoise: Distinguish missing workload option
  rtla/timerlat_hist: Set OSNOISE_WORKLOAD for kernel threads
  rtla/timerlat_top: Set OSNOISE_WORKLOAD for kernel threads
