I found several references in the 2.6.7 time-frame, but it wasn't clear how far things got. I noticed that SuSE has adopted pagg in there IPF version. Incidentally, has any other large distros added it? 2) There doesn't appear to be any documentation on how to use PAGGs in a new module. I'm looking to use PAGGs for a in house project. Is there any effort underway to explain how to use PAGGs other than the source code?

If there is interest, I'd personally be happy to put some docs together if I could get some input as to what is desired. http://marc.theaimsgroup.com/?l=linux-kernel&m=110624592118941&w=2 We're also very interested in any ideas on how to get this accepted in to the kernel. It was once in akpm's tree for a short time, but was later removed (I think due to lack of users in my opinion).
