![]() Avoid memory copy on writes. (This patch depends on fixes in patch 9 to follow.) Although skb->len should not be set when working with linear skbuffs, the skb->tail pointer maintained by skb_put/skb_trim is not relevant to what happens when the skb_fill_page_desc function is called. This issue was raised without comment in linux-kernel and netdev earlier this month: http://thread.gmane.org/gmane.linux.kernel/446474/ http://thread.gmane.org/gmane.linux.network/45444/ So until there is something analogous to skb_put that works for zero-copy write skbuffs, we will do what the other callers of skb_fill_page_desc are doing.
