From a6fcdd8d95f7486150b3faadfea119fc3dfc3b74 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=E6=99=8F=E8=89=B3=28=E9=87=87=E8=8B=93=29?= Date: Sat, 6 May 2023 15:42:53 +0800 Subject: [PATCH] sched/debug: Correct printing for rq->nr_uninterruptible Commit e6fe3f422be1 ("sched: Make multiple runqueue task counters 32-bit") changed the type for rq->nr_uninterruptible from "unsigned long" to "unsigned int", but left wrong cast print to /sys/kernel/debug/sched/debug and to the console. For example, nr_uninterruptible's value is fffffff7 with type "unsigned int", (long)nr_uninterruptible shows 4294967287 while (int)nr_uninterruptible prints -9. So using int cast fixes wrong printing.
