From 25e8978817a54745c44d956d8303e6be6f2c4047 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Mon, 16 Jul 2018 09:37:31 +0100 Subject: qdev: add HotplugHandler->post_plug() callback The ->pre_plug() callback is invoked before the device is realized. The ->plug() callback is invoked when the device is being realized but before it is reset. This patch adds a ->post_plug() callback which is invoked after the device has been reset. This callback is needed by HotplugHandlers that need to wait until after ->reset().
