![]() We introduced a couple of helpers for copying iomem over iov_iter, and the functions were formed like the former copy_from/to_user(), and the return value was adjusted to 0/-EFAULT, which made the code transition a bit easier at that time. OTOH, the standard copy_from/to_iter() functions have different argument orders and the return value, and this difference can be confusing. It's not only confusing but dangerous; actually I did write a wrong code due to that once :-< For reducing the confusion, this patch changes the syntax of those helpers to align with the standard copy_from/to_iter(). The argument order is changed and the return value is the size of copied bytes. The callers of those functions are updated accordingly, too.
