Subject: [PATCH v3 5/8] cpus: Use qemu_cond_wait_iothread() where proper
Date: Wed, 28 Jul 2021 14:31:48 -0400 [thread overview]
Message-ID: <20210728183151.195139-6-peterx@redhat.com> (raw)
In-Reply-To: <20210728183151.195139-1-peterx@redhat.com>
The helper is introduced but we've still got plenty of places that are directly
referencing the qemu_global_mutex itself. Spread the usage.
