Christoph Hellwig c41108049d kyber: avoid q->disk dereferences in trace points ... q->disk becomes invalid after the gendisk is removed. Work around this by caching the dev_t for the tracepoints. The real fix would be to properly tear down the I/O schedulers with the gendisk, but that is a much more invasive change.
