474 | * "Dyntick with callbacks": Entering dyntick-idle despite callbacks. | |
475 | * "Dyntick with lazy callbacks": Entering dyntick-idle w/lazy callbacks. | |
476 | * "More callbacks": Still more callbacks, try again to clear them out. | |
477 | * "Callbacks drained": All callbacks processed, off to dyntick idle! | |
478 | * "Timer": Timer fired to cause CPU to continue processing callbacks. | |
479 | * "Demigrate": Timer fired on wrong CPU, woke up correct CPU. | |
480 | * "Cleanup after idle": Idle exited, timer canceled. | |
