I just stuck in some counters in expand() that looked to see whether the
list was empty or not when the page is added and then printed them out
occasionally.

It will be interesting to see the results both on a freshly-booted
system and one that's reached relatively steady-state and is moving
around a minimal number of pageblocks between the different types.

In any case, the end result here needs to be some indication that the
patch either helps ease fragmentation or helps performance.
