On ARCH_BRCMSTB using 32-bit and 64-bit kernels, still seeing the following futex warning, unfortunately simply running the function tracers does not allow me to trigger the warning, so I am having a hard time coming up with a simple reproducer:

I thought the patches from Ben would help resolve this, but it looks like something else is still needed :(
thanks for testing and letting me know.
