[Qemu-devel] [PATCH v2 1/3] migration: add qemu_file_update_transfer int


From: Ivan Ren
Subject: [Qemu-devel] [PATCH v2 1/3] migration: add qemu_file_update_transfer interface
Date: Mon, 29 Jul 2019 16:01:19 +0800

Add qemu_file_update_transfer for just update bytes_xfer for speed
limitation. This will be used for further migration feature such as
multifd migration.
