From bf0ddaba65ddbb2715af97041da8e7a45b2d8628 Mon Sep 17 00:00:00 2001 From: Omar Sandoval Date: Thu, 26 Apr 2018 00:21:59 -0700 Subject: blk-mq: fix sysfs inflight counter When the blk-mq inflight implementation was added, /proc/diskstats was converted to use it, but /sys/block/$dev/inflight was not. Fix it by adding another helper to count in-flight requests by data direction.
