rv/monitor: Add the wwnr monitor Per task wakeup while not running (wwnr) monitor. This model is broken, the reason is that a task can be running in the processor without being set as RUNNABLE. Think about a task about to sleep: 1: set_current_state(TASK_UNINTERRUPTIBLE); 2: schedule(); And then imagine an IRQ happening in between the lines one and two, waking the task up. BOOM, the wakeup will happen while the task is running. Q: Why do we need this model, so? A: To test the reactors.

tools/rv: Fix cleanup after failed trace setup [ Upstream commit 33ec2269a4155cad7e9e42c92327dcaa9aee59a7 ] Currently if ikm_setup_trace_instance() fails, the tool returns without any cleanup, if rv was called with both -t and -r, this means the reactor is not going to be cleared. Jump to the cleanup label to restore the reactor if necessary.
