Comment (by earnjam):

 Just thought about a scenario here...since we cache the return from
 `get_dirsize()` as a transient, it's possible that if it was called
 directly outside of core with the new exclude parameter passed to it, it
 would cache that value instead of the expected core usage.

 Not sure the best way to prevent that.

 Perhaps don't cache the value if the exclude parameter is passed to it
 unless it is for the main site uploads directory?
