Subject: [PATCH v9 66/74] s390x: convert to cpu_has_work_with_iothread_lock
Date: Thu, 21 May 2020 12:40:03 -0400	[thread overview]
Message-ID: <20200521164011.638-67-robert.foley@linaro.org> (raw)
In-Reply-To: <20200521164011.638-1-robert.foley@linaro.org>

From: "Emilio G. Cota" <cota@braap.org>

Soon we will call cpu_has_work without the BQL.
