From bc698c367d6fac15454ee3ff6bb168e43c151465 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Mon, 20 Jun 2022 12:01:52 +0100 Subject: [PATCH] migration: rename qemu_file_update_transfer to qemu_file_acct_rate_limit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The qemu_file_update_transfer name doesn't give a clear guide on what its purpose is, and how it differs from the qemu_file_credit_transfer method. The latter is specifically for accumulating for total migration traffic, while the former is specifically for accounting in thue rate limit calculations. The new name give better guidance on its usage. Signed-off-by: Daniel P.
