[Qemu-devel] [PULL 04/15] iotests: Check dirty bitmap statistics in 124

[Kevin Wolf <kwolf@redhat.com>]

From: Eric Blake <eblake@redhat.com>

We had a bug for multiple releases where dirty-bitmap count was
documented in bytes but reported in sectors; enhance the testsuite
to add coverage of DirtyBitmapInfo to ensure we do not regress again.
