From c23ec1c095a13e1279660ea9b27290c9ae0f3849 Mon Sep 17 00:00:00 2001
Message-Id: <c23ec1c095a13e1279660ea9b27290c9ae0f3849@dist-git>
From: Peter Krempa <pkrempa@redhat.com>

Subject: [PATCH] qemu: blockjob: Remove 'disabledBitmapsBase' field from
commit job private data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
New semantics of the bitmap handling don't need this. Remove the field
and all uses of it including the status XML.
