Ooops, sorry.

Right.
I did check that there were other symlinks already in the tree, but you're correct I seem to be the first clever person to add symlinks to source files.

Kbuild is not involved really, these files are just built with plain Makefiles, at least from the symlink side.
FWIW ctags seems to cope, that's what I use.
But I didn't think of cscope.
Given you're the only person who's noticed I suspect most other things haven't broken, fingers crossed :)
