There are very few places that have cause to do that - all in core VFS now, and all done to files that are not yet opened (or visible to anybody else, for that matter). Let's turn f_path into a union of struct path __f_path and const struct path f_path. It's C, not C++ - 6.5.2.3[4] in C99 and later explicitly allows that kind of type-punning. That way any attempts to bypass these checks will be either very easy to catch, or (if the bastards get sufficiently creative to make it hard to spot with grep alone) very clearly malicious - and still catchable with a bit of instrumentation for sparse.
