The VFS > system is probably a close second (namei() anyone?). The NFS is pretty clean, as long as you take the macros at face value when reading the code. The VFS code is trivial, if you just understand call-by-descriptor, which OpenSSL, libXt, libXaw, libXm, etc., all use. It's a common technique. The linker set code is odd. The build process for device modules is pretty opaque, especially when moving drivers between 4.x and 5.x. Anything with "perl" code in it: it's a write-only programming language, useful only for throw-away code.
