From bda07a64c09c44ced789dbb815c71854f0c59839 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 29 Sep 2015 07:42:40 -0700 Subject: tcp: remove unused len argument from tcp_rcv_state_process() Once we realize tcp_rcv_synsent_state_process() does not use its 'len' argument and we get rid of it, then it becomes clear this argument is no longer used in tcp_rcv_state_process() Signed-off-by: Eric Dumazet Signed-off-by: David S.
