From: Herbert Xu <herbert@gondor.apana.org.au> Date: Sat, 21 Mar 2015 14:14:03 +1100 > netlink: Remove netlink_compare_arg.trailer > > Instead of computing the offset from trailer, this patch computes > netlink_compare_arg_len from the offset of portid and then adds 4 > to it. This allows trailer to be removed. > > Reported-by: David Miller <davem@davemloft.net> > Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Applied, thanks! -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
