....... Nice one! As the only addition here is debugging output, I can only assume that the two patches were being booted in isolation instead of combination earlier. The two threads have been a little confused with hand waving so that can easily happen.

I'll post a patch suitable for pick-up shortly. The two patches ran in combination with CONFIG_DEBUG_SLAB a compile-based stress tests without difficulty so hopefully there is not new surprises hiding in the corners.
