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.
