From 567628163ec8c6b76ba3117c3062edc0521dc185 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Wed, 29 Jan 2020 11:22:38 +0100 Subject: [PATCH] monitor: Collect "control" command handlers in qmp-cmds.control.c Move all of the QMP commands handlers to implement the 'control' module (qapi/control.json) that can be shared between the system emulator and tools such as a storage daemon to a new file monitor/qmp-cmds-control.c.
