Ok, applied as commit 1c24a186398f ("fs: fd tables have to be
multiples of BITS_PER_LONG").

I tried to add reasonable commentary too, both to the commit and the
file.c code.

Christian already tested that added ALIGN() for his test-case (that's
obviously assuming the obvious patch was identical - it can go in
multiple places), but the more the merrier, of course.
