That's not completely true. There are a lot of static inlines out there,
which basically made it possible for external modules to use FPU (in some
way) when they had kernel_fpu_[begin|end]() available.

I personally don't care about ZFS a tiny little bit; but in general, the
current situation with _GPL and non-_GPL exports is simply not nice. It's
not really about licensing (despite the name), it's about 'internal vs
external', which noone is probably able to define properly.

If it would be strictly about license compatibility, that'd at least make
us somewhat deterministic.
