In vm_operations_struct there are pointers for (*advise), (*nopage), (*wppage), et cetera. wppage is never used or called by any code (copy-on-write is the default behaviour). Why is this? What if I want my own wppage handler? Having the fn ptr member but not using it doesn't make sense, IMHO. Also, I believe (*advise) isn't used either. Some other small things: 1. struct vm_area_struct -> struct vm_area ? 2. struct vm_operations_struct -> struct vm_area_operations ? 3. /dev/sysvipc/shm/1234 or /proc/sysvipc/shm/1234 ?? (This last suggestion just might start a holy war.... :-) Thanks, Lennert Buytenhek -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
