Subject: [PULL 16/30] migration/postcopy: wait for decompress thread in precopy
Date: Tue, 14 Jan 2020 12:39:12 +0100 [thread overview]
Message-ID: <20200114113926.3556-17-quintela@redhat.com> (raw)
In-Reply-To: <20200114113926.3556-1-quintela@redhat.com>
From: Wei Yang <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.
