[1/1] blk-mq-debugfs: Show active requests per queue for shared tags commit: 9b84c629c90374498ab5825dede74a06ea1c775b Best regards,
diff --git a/block/blk-mq-debugfs.c b/block/blk-mq-debugfs.c index 68ca5d21cda7..0f8c60e9c719 100644 --- a/block/blk-mq-debugfs.c +++ b/block/blk-mq-debugfs.c @@ -550,7 +550,7 @@ static int hctx_active_show(void *data, struct seq_file *m) { struct blk_mq_hw_ctx *hctx = data; - seq_printf(m, "%d\n", atomic_read(&hctx->nr_active)); + seq_printf(m, "%d\n", __blk_mq_active_requests(hctx)); return 0; }
Currently we show the hctx.active value for the per-hctx "active" file. However this is not maintained for shared tags, and we instead keep a record of the number active requests per request queue - see commit f1b49fdc1c64 ("blk-mq: Record active_queues_shared_sbitmap per tag_set for when using shared sbitmap). Change for the case of shared tags to show the active requests per request queue by using __blk_mq_active_requests() helper. Signed-off-by: John Garry <john.garry@huawei.com>
