Therefore, EROFS can support rolling hash easily and our mechanism can make full use of filesystem interfaces (byte-addressed) naturally. Before that, I'd like to submit some trivial cleanups in advance for the 5.19 cycle. All patches are without any logical change, so I can have a more recent codebase for the next rework cycle.
