From ab31979a7e835832605f8425d0eaa5c74d1e6375 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 2 May 2014 13:26:42 +0200 Subject: qmp: Don't use error_is_set() to suppress additional errors Using error_is_set(errp) that way can sweep programming errors under the carpet when we get called incorrectly with an error set. encrypted_bdrv_it() does it, because there's no way to make bdrv_iterate() break its loop. Actually safe, because qmp_cont() clears the error before the loop. Clean it up anyway: replace bdrv_iterate() by bdrv_next(), break the loop on error. Replace both occurrences, for consistency.
