The reason for these two sub-helpers was to force me to structure the code so that Matthews original idea of replacing ->iomap_begin and ->iomap_end with a single next callback so that iomap_iter could be inlined into callers and the indirect calls could be elided is still possible. This would only be useful for a few specific methods (probably dax and direct I/O) where we care so much, but it seemed like a nice idea conceptually so I would not want to break it. OTOH we could just remove this function for now and do that once needed. > Modulo the question about iomap_iter_done, I guess this looks all right > to me.
