From ffeee417d97f9171bce9f43c22c9f477e4c84f54 Mon Sep 17 00:00:00 2001 From: Chunguang Xu Date: Tue, 13 Apr 2021 09:39:05 +0800 Subject: cgroup: use tsk->in_iowait instead of delayacct_is_task_waiting_on_io() If delayacct is disabled, then delayacct_is_task_waiting_on_io() always returns false, which causes the statistical value to be wrong. Perhaps tsk->in_iowait is better.
