> updateNameDirSize() has only metrics functionality (i.e. not very critical)
> but has a fair bit of performance impact in one of the more critical methods
> (rollEditLog). It's better to either reduce the metrics update frequency or
> make it update asynchronously to avoid interference with rollEditLog().
