Ack, this makes sense to me. It's crazy to let fcntl etc show bits
that the kernel isn't even using.
I'm assuming this will come through Al eventually. It doesn't seem
high-priority for me to worry about it just before the 4.11 release,
but it might be worth marking for stable just to percolate the change
eventually to other kernels, and keep these kinds of differences
minimal.
