Subject: [PATCH] vhost/crypto: fix descriptor move
Date: Wed,  9 May 2018 15:08:39 +0100	[thread overview]
Message-ID: <20180509140839.85818-1-roy.fan.zhang@intel.com> (raw)

This patch fixes the redundant descriptor move in the copy mode
of vhost crypto. Originally the redundant descriptor move will
cause the message parsing error.
