From 582a098e6ca00dd42f317dad8affd13e5a20bc42 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 27 Jul 2022 11:21:33 +0200 Subject: [PATCH] qga: Replace 'blacklist' command line and config file options by 'block-rpcs' MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let's use a more appropriate wording for this command line and config file option. The old ones are still accepted for compatibility reasons, but marked as deprecated now so that it could be removed in a future version of QEMU. This change is based on earlier patches from Philippe Mathieu-Daudé, with the idea for the new option name suggested by BALATON Zoltan. And while we're at it, replace the "?" in the help text with "help" since that does not have the problem of conflicting with the wildcard character of the shells.
