Subject: [Patch v2 2/6] migration/postcopy: wait for decompress thread in precopy
Date: Thu,  7 Nov 2019 20:39:03 +0800	[thread overview]
Message-ID: <20191107123907.29791-3-richardw.yang@linux.intel.com> (raw)
In-Reply-To: <20191107123907.29791-1-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.
