block: Update to io-controller stats
Changelog from v1: o Call blkiocg_update_idle_time_stats() at cfq_rq_enqueued() instead of at dispatch time. Changelog from original patchset: (in response to Vivek Goyal's comments) o group blkiocg_update_blkio_group_dequeue_stats() with other DEBUG functions o rename blkiocg_update_set_active_queue_stats() to blkiocg_update_avg_queue_size_stats() o s/request/io/ in blkiocg_update_request_add_stats() and blkiocg_update_request_remove_stats() o Call cfq_del_timer() at request dispatch() instead of blkiocg_update_idle_time_stats() Signed-off-by: Divyesh Shah<dpshah@google.com> Acked-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
