Hi, thanks for testing, I think you first reproduce this issue(got WARNING
at device_add_disk) by your own build, then add my debug patch.
I'm going to try testing warnings with a kernel I've built, to try to
determine if warnings are working at all for the ones I'm building. However
it might be that the WARN_ONs are not being reached for the kernels I've
built. If that turns out to be the case, I may not be able to get you both
the output from the WARN_ONs and the output from your debugging patch at
the same time.
My next kernel build isn't going to finish in time to test today.
