There is no equivalent AFAIK. There were some people doing things like this
for earlt 2.6 versions. Patches were posted to this list (years ago now I
guess), but they never stabilised enough for use or inclusion.
The good news is that with 3 allocators in the 2.6 kernel (slab/slob/slub),
the interface and requirements should be a lot more defined to allow creation
of yet another that works like the old page_alloc2, if that is what is
