This is why Linus says just leave /usr/src/linux alone, its because distributions insist on having the broken /usr/include/ symlinks. since debian does not have these symlinks and does not even install any kernel source in /usr/src/linux this is all irrelevant on Debian. you can add a /usr/src/linux symlink on debian but it doesn't affect anything since /usr/include has no symlinks pointing there. where it *DOES* break things is redhat, and everything following redhat's lead.
