I have often thought exactly the same thing. It seems so natural to
combine unaligned reads and writes with byte-reordering. I even brought
up the issue on LKML: Why shouldn't there be architecture-dependent
versions of
get_unaligned_le16(), get_unaligned_le32(), get_unaligned_le64(),
get_unaligned_be16(), get_unaligned_be32(), get_unaligned_be64(),
and the corresponding put_unaligned...() things?
But for some unclear reason people weren't in favor of it. And as a
result, the kernel is filled with roll-your-own versions of these things.
