which is already happening today you mean.  grep the kernel headers and you=
'll=20
see a ton of [u]intXX_t hits.

this logic though means that the kernel should not be defining any structur=
es=20
that the C library is defining (such as asm-generic/fcntl.h).  such structs=
=20
should get renamed the same way as __[us]XX types.
