Subject: [Qemu-devel] [PATCH v2 3/5] iothread: create main loop unconditionally
Date: Wed,  6 Mar 2019 19:55:30 +0800	[thread overview]
Message-ID: <20190306115532.23025-4-peterx@redhat.com> (raw)
In-Reply-To: <20190306115532.23025-1-peterx@redhat.com>

Since we've have the gcontext always there, create the main loop
altogether.  The iothread_run() is even cleaner.
