Subject: [Qemu-devel] [PATCH 11/21] jobs: remove job_defer_to_main_loop
Date: Tue,  7 Aug 2018 00:33:39 -0400	[thread overview]
Message-ID: <20180807043349.27196-12-jsnow@redhat.com> (raw)
In-Reply-To: <20180807043349.27196-1-jsnow@redhat.com>

The job infrastructure handles this now, so remove this call.
