It's relevant to say that Xen re-uses some Linux kernel source codes,
and chooses a similar directory structure, Xen authors gain much
knowledge and inspiration from Linux kernel.

The similarity ends here.

If you tried to make a patch between Linux kernel and Xen, I'm afraid
you would end up with patch that deletes most files in Linux kernel
and introduces most new codes in Xen.

A patch is relevant between conventional Linux kernel and XenoLinux
kernel.
