Yes, but perhaps you can also look at another series

[PATCH 1/3] x86, fpu: __kernel_fpu_begin() should clear fpu_owner_task even if use_eager_fpu()

[PATCH 2/3] x86, fpu: always allow FPU in interrupt if use_eager_fpu()

[PATCH 3/3] x86, fpu: don't abuse FPU in kernel threads if use_eager_fpu()

? (off course I will be happy to resend)

It was sent before the recently applied changes. And in fact in theory
728e53fef429a0f "x86/fpu: Also check fpu_lazy_restore() when use_eager_fpu()"
depends on 1/3 above.
