From 46cdc45acb089c811d9a54fd50af33b96e5fae9d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 20 Jan 2022 10:28:13 -0700 Subject: block: fix async_depth sysfs interface for mq-deadline A previous commit added this feature, but it inadvertently used the wrong variable to show/store the setting from/to, victimized by copy/paste. Fix it up so that the async_depth sysfs interface reads and writes from the right setting. Fixes: 07757588e507 ("block/mq-deadline: Reserve 25% of scheduler tags for synchronous requests") Link: https://bugzilla.kernel.org/show_bug.cgi?id=215485 Reviewed-by: Bart Van Assche Signed-off-by: Jens Axboe --- block/mq-deadline.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'block') diff --git a/block/mq-deadline.c b/block/mq-deadline.c index 85d919bf60c7..3ed5eaf3446a 100644 --- a/block/mq-deadline.c +++ b/block/mq-deadline.c @@ -865,7 +865,7 @@ SHOW_JIFFIES(deadline_write_expire_show, dd->fifo_expire[DD_WRITE]); SHOW_JIFFIES(deadline_prio_aging_expire_show, dd->prio_aging_expire); SHOW_INT(deadline_writes_starved_show, dd->writes_starved); SHOW_INT(deadline_front_merges_show, dd->front_merges); -SHOW_INT(deadline_async_depth_show, dd->front_merges); +SHOW_INT(deadline_async_depth_show, dd->async_depth); SHOW_INT(deadline_fifo_batch_show, dd->fifo_batch); #undef SHOW_INT #undef SHOW_JIFFIES @@ -895,7 +895,7 @@ STORE_JIFFIES(deadline_write_expire_store, &dd->fifo_expire[DD_WRITE], 0, INT_MA STORE_JIFFIES(deadline_prio_aging_expire_store, &dd->prio_aging_expire, 0, INT_MAX); STORE_INT(deadline_writes_starved_store, &dd->writes_starved, INT_MIN, INT_MAX); STORE_INT(deadline_front_merges_store, &dd->front_merges, 0, 1); -STORE_INT(deadline_async_depth_store, &dd->front_merges, 1, INT_MAX); +STORE_INT(deadline_async_depth_store, &dd->async_depth, 1, INT_MAX); STORE_INT(deadline_fifo_batch_store, &dd->fifo_batch, 0, INT_MAX); #undef STORE_FUNCTION #undef STORE_INT -- cgit v1.2.3-58-ga151
