From d626f62b11e00c16e81e4308ab93d3f13551812a Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 27 Mar 2007 18:55:52 -0300 Subject: [SK_BUFF]: Introduce skb_copy_from_linear_data{_offset} To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes.
