[Qemu-devel] [PATCH 05/12] migration: clean up server sockets and handle


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH 05/12] migration: clean up server sockets and handlers before invoking process_incoming_migration
Date: Fri, 2 Nov 2012 18:50:58 +0100

A first step towards making a common "suffix" for all migration protocols,
and moving it to process_incoming_migration.
