Subject: [PATCH 1/1] proc/stat: Fix wrong guest nice cpustat value
Date: Thu, 5 Dec 2019 03:03:44 +0100 [thread overview]
Message-ID: <20191205020344.14940-1-frederic@kernel.org> (raw)
From: Flavio Leitner <fbl@sysclose.org>
The value being used for guest_nice should be CPUTIME_GUEST_NICE
and not CPUTIME_USER.
