I'm not sure all this page_address() stuff makes any sense on highmem systems. How about page_to_pfn()? I also have to wonder if you should be hooking into count_vm_event() and using those. Could you give a high-level overview of exactly why you need these hooks, and perhaps what you expect from future people adding things to the VM? -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
