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.
