I'm sorry to be so blunt but this is completely wrong/ backwards: Prior
to libc6, /usr/include/linux used to be a symlink to the actual source
tree the kernel was compiled from. This practice was dropped because
applications using a certain, compiled version of glibc need to be
compiled with the same kernel headers as the C library was to ensure
that both agree wrt structure definitions. Since then, glibc included a
certain set of kernel headers.

Linux has the nice policy of never changing a public ABI, hence, there's
no problem in this respect (I'm right now running with a 4.5.0 kernel on
a Wheezy system because some code changes of mine went into Linux when
that was current).
