  "message": "rcu: Add warning for RCU_FAST_NO_HZ timer firing\n\nRCU_FAST_NO_HZ uses a timer to limit the time that a CPU with callbacks\ncan remain in dyntick-idle mode.  This timer is cancelled when the CPU\nexits idle, and therefore should never fire.  However, if the timer\nwere migrated to some other CPU for whatever reason (1) the timer could\nactually fire and (2) firing on some other CPU would fail to wake up the\nCPU with callbacks, possibly resulting in sluggishness or a system hang.\n\nThis commit therfore adds a WARN_ON_ONCE() to the timer handler in order\nto detect this condition.\n\nSigned-off-by: Paul E.
