Subject: [Qemu-devel] [PATCH v10 6/7] monitor: move init global earlier
Date: Fri,  8 Jun 2018 11:55:10 +0800	[thread overview]
Message-ID: <20180608035511.7439-7-peterx@redhat.com> (raw)
In-Reply-To: <20180608035511.7439-1-peterx@redhat.com>

Before this patch, monitor fd helpers might be called even earlier than
monitor_init_globals().  This can be problematic.

After previous work, now monitor_init_globals() does not depend on
accelerator initialization any more.  Call it earlier (before CLI
parsing; that's where the monitor APIs might be called) to make sure it
is called before any of the monitor APIs.
