From 3e0a233d869e74e78b516be34715b91528508cfc Mon Sep 17 00:00:00 2001 From: Peter Lieven Date: Tue, 24 Sep 2013 15:35:08 +0200 Subject: block/get_block_status: set *pnum = 0 on error if the call is invoked through bdrv_is_allocated the caller might expect *pnum = 0 on error. however, a new implementation of bdrv_get_block_status might only return a negative exit value on error while keeping *pnum untouched.
