Not sure, but I guess better to do it directly with page_alloc...or at least kmalloc() to better utilize slab. The thing that I think is hard to do, is to implement protection scheme to make sure say process A won't access page allocated by process B. Hopefully I understand your goal correctly. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
