Fields that are specifically in some endianness that isn't
(necessarily) the CPU's _should_ be documented as such in the manpage,
but I dunno if __{le,be}{16,32,64} as a type name is the ideal way to
do it. There is no off-the-shelf notation for this as far as I know.
I do not know what __sum16, __wsum, and __poll_t are used for, but I
want to remind everyone again that the kernel's concerns are not
necessarily user space's concerns and the information that should
appear in the manpages is the information that is most relevant to
user space programmers.
