Merge tag 'trace-rv-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull runtime verifier and osnoise fixes from Steven Rostedt: - Reset idle tasks on reset for runtime verifier When the runtime verifier is reset, it resets the task's data that is being monitored. But it only iterates for_each_process() which does not include the idle tasks. As the idle tasks can be monitored, they need to be reset as well. - Fix the enabling and disabling of tracepoints in osnoise If timerlat is enabled and the WORKLOAD flag is not set, then the osnoise tracer will enable the migrate task tracepoint to monitor it for its own workload. The test to enable the tracepoint is done against user space modifiable parameters. On disabling of the tracer, those same parameters are used to determine if the tracepoint should be disabled. The problem is if user space were to modify the parameters after it enables the tracer then it may not disable the tracepoint. Instead, a static variable is used to keep track if the tracepoint was enabled or not. Then when the tracer shuts down, it will use this variable to decide to disable the tracepoint or not, instead of looking at the user space parameters. * tag 'trace-rv-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/osnoise: Fix resetting of tracepoints rv: Reset per-task monitors also for idle tasks
