Hi guys, Can someone explain what get_fs(), set_fs() .... set_fs(KERNEL_DS) means? Cos' I can't find any explaination on them. I guess is related to memory management. Does a UDP socket needs these? Many Thanks, have a nice day. DOn - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
