Unlike the "val[]" thing, I don't think anybody is supposed to access
those fields directly.

Well, glibc already calls it __val …

Hmm. If user space already doesn't see the "val[]" array anyway, I
guess we could just do that in the kernel too.

Looking at the glibc headers I have for fds_bits, glibc seems to do
*both* fds_bits[] and __fds_bits[] depending on __USE_XOPEN or not.

Anyway, that all implies to me that we might as well just go the truly
mindless way, and just do the double underscores and not bother with
renaming any files.

I thought people actually might care about the "val[]" name because I
find that in documentation, but since apparently it's already not
visible to user space anyway, that can't be true.

I guess that makes the original patch acceptable, and we should just
do the same thing to fds_bits..
