Subject: [PATCH 3/3] vhost: add some log for vhost message VHOST_USER_SET_VRING_BASE
Date: Mon, 13 Dec 2021 12:29:45 +0800 [thread overview]
Message-ID: <1639369785-103190-1-git-send-email-andy.pei@intel.com> (raw)
Usually the last avail index and last used index is 0, but for target
device of live migration, the last avail index and last used index is
not 0. So I think some log is helpful.
