[PATCH v3 5/8] cpus: Use qemu_cond_wait_iothread() where proper


From: Peter Xu
Subject: [PATCH v3 5/8] cpus: Use qemu_cond_wait_iothread() where proper
Date: Wed, 28 Jul 2021 14:31:48 -0400

The helper is introduced but we've still got plenty of places that are directly
referencing the qemu_global_mutex itself.  Spread the usage.
