Subject: [Qemu-devel] [PULL 27/36] block/backup: improve sync=bitmap work estimates
Date: Fri, 16 Aug 2019 19:13:09 -0400
Message-ID: <20190816231318.8650-28-jsnow@redhat.com> (raw)
In-Reply-To: <20190816231318.8650-1-jsnow@redhat.com>

When making backups based on bitmaps, the work estimate can be more
accurate. Update iotests to reflect the new strategy.

TOP work estimates are broken, but do not get worse with this commit.
That issue is addressed in the following commits instead.
