Subject: [PATCH v12 13/26] libxl_internal: move stream read manipulations to right place
Date: Wed, 23 Mar 2016 16:06:27 +0800	[thread overview]
Message-ID: <1458720400-4699-14-git-send-email-xiecl.fnst@cn.fujitsu.com> (raw)
In-Reply-To: <1458720400-4699-1-git-send-email-xiecl.fnst@cn.fujitsu.com>

No functional changes and this cleanup will make the later
patch called "primary vm suspend/resume/checkpoint code" not
too complicated.
