It is compile breakage and was also discussed on
fedora-devel-list@xxxxxxxxxx with Mauro and myself CC'd.  The control
number will be reserved forever to avoid binary breakage.

However, as Mauro noted in that conversation: "Those controls haven't
been used by any Kernel drivers for a long time (I suspect that they
were never used)."  Since no driver had ever implemented the control I
figured user space application wouldn't be using it either.

If David wants to revert the _DEPRECATED tags that is fine; we can add a
feature removal for a year from now if it gets merged.

Thanks,
