hi all: I want to mmap a kernel memory area which sk_buf->data pointer into userspace. I want to do this , because this way can reduce a copy from kernel to userspace. How to fix it? Or, which book or project can help me ? Thank you. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
