Not much cleaner compared to what? I think padding stuff is bound to be
somewhat complex. It's a nasty thing in nature. I think ->extra_len is
better than ->raw_data_len because ->extra_len only needs to be updated
where the dirty jobs are done and extra buffer areas are added. Any
better suggestions?
