From df9a681dc9ad41c9cdeb9ecc5d060ba9abd27e01 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Mon, 9 Nov 2015 18:16:54 +0800 Subject: qed: Implement .bdrv_drain The "need_check_timer" is used to clear the "NEED_CHECK" flag in the image header after a grace period once metadata update has finished. In compliance to the bdrv_drain semantics we should make sure it remains deleted once .bdrv_drain is called. We cannot reuse qed_need_check_timer_cb because here it doesn't satisfy the assertion. Do the "plug" and "flush" calls manually.
