From 4f6fd3491cf0f768b135ed2e242bd1d1d2a2efec Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Fri, 23 Aug 2013 09:14:47 +0800 Subject: block: make bdrv_delete() static Manage BlockDriverState lifecycle with refcnt, so bdrv_delete() is no longer public and should be called by bdrv_unref() if refcnt is decreased to 0. This is an identical change because effectively, there's no multiple reference of BDS now: no caller of bdrv_ref() yet, only bdrv_new() sets bs->refcnt to 1, so all bdrv_unref() now actually delete the BDS.
