As a result the kernel does not have endian types for single
byte variables (ie. there's __be16, __be32, __be64 but not __be8),
nor are there cpu_to_be8 or be8_to_cpu conversion functions.
Hence the lack of them in the XFS code ;)

Well, that should be obvious when changing the structure
that has lots of __beX types in already....
