From e54ee1b385a9d084b4052b6db7391ea2fd799fa8 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Mon, 6 Jul 2020 15:39:53 -0500 Subject: block: Add support to warn on backing file change without format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For now, this is a mechanical addition; all callers pass false. But the next patch will use it to improve 'qemu-img rebase -u' when selecting a backing file with no format.
