Nope.  I've done a few modifications:

1) the IMHO inflexible classzone stuff has been removed

2) we have reverse mappings, so we can do our pageout
   scan by physical address

3) this in turn means the active, inactive_dirty and
   inactive_clean lists are per zone ... allowing us
   to scan only in those zones where we actually need
   to free pages

regards,

Rik
