Re: [Devel] [PATCH 6/6] BC: kernel memory accounting (marks)

I'm still a bit concerned about if we actually need the 'struct page'
pointer. I've gone through all of the users, and I'm not sure that I
see any that _require_ having a pointer in 'struct page'. I think it
will take some rework, especially with the pagetables, but it should be
quite doable.

Store in vm_struct
mount hashtable:
Don't need alignment. use the slab?
either store in an extra field of 'struct page', or use the
mm's. mm should always be available when alloc/freeing a
pagetable page

Did I miss any?
