From 1c3a555c35f2124d45a295eb715e50512526810e Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Wed, 3 May 2017 00:35:51 +0800 Subject: [PATCH] file-win32: Error out if locking=on We share the same set of QAPI options with file-posix, but locking is not supported here. So error out if it is specified as 'on' for now.
