Subject: [PATCH v5 06/31] accel/kvm: Implement AccelOpsClass::has_work()
Date: Mon, 20 Sep 2021 23:44:22 +0200	[thread overview]
Message-ID: <20210920214447.2998623-7-f4bug@amsat.org> (raw)
In-Reply-To: <20210920214447.2998623-1-f4bug@amsat.org>

Implement KVM has_work() handler in AccelOpsClass and
remove it from cpu_thread_is_idle() since cpu_has_work()
is already called.
