From 9b84c629c90374498ab5825dede74a06ea1c775b Mon Sep 17 00:00:00 2001 From: John Garry Date: Fri, 29 Oct 2021 16:40:23 +0800 Subject: blk-mq-debugfs: Show active requests per queue for shared tags 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.
