Roland> Does it seem reasonable to add a new system call to let Roland> userspace mark memory it doesn't want copied into forked Roland> processes? Something like Roland> long sys_mark_nocopy(unsigned long addr, size_t len, int Roland> mark) Roland> which would set VM_DONTCOPY if mark != 0, and clear it if Roland> mark == 0. A better name would be gratefully accepted... Christoph> add a new MAP_DONTCOPY flag and accept it in mmap and Christoph> mprotect? That is much better, thanks. But I think it would need to be PROT_DONTCOPY to work with mprotect(), right? - R. - 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/
