Subject: [PATCH 2/6] migration/postcopy: wait for decompress thread in precopy
Date: Fri, 18 Oct 2019 08:48:46 +0800 [thread overview]
Message-ID: <20191018004850.9888-3-richardw.yang@linux.intel.com> (raw)
In-Reply-To: <20191018004850.9888-1-richardw.yang@linux.intel.com>
Compress is not supported with postcopy, it is safe to wait for
decompress thread just in precopy.
This is a preparation for later patch.
