I really hate that one. Every time we exposed the internal details to
the fucking early init code, we paid for that afterwards. And this
goes over the top wrt the level of details being exposed.

_IF_ you want to keep that thing, move it to fs/file.c, with dire comment
re that being very special shite for init and likely cause of subsequent
trouble whenever anything gets changed, a gnat farts somewhere, etc.

Do not leave that kind of crap sitting around init/*.c; KERNEL_DS
may be a source of occasional PITA, but here you are trading it for a lot
worse one in the future.
