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

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