> In {{LogCleaner.LogToClean}}, the following computations, which are used to
> compute the cleanable ratio, can overflow since the segment size is an
> integer.
> {code}
> val cleanBytes = log.logSegments(-1, firstDirtyOffset).map(_.size).sum
> ...
> val cleanableBytes = log.logSegments(firstDirtyOffset,
> math.max(firstDirtyOffset, firstUncleanableOffset)).map(_.size).sum
> {code}
