From a56476962e92a6c389a1a561274d4a27607b7b5f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 5 Jul 2005 15:20:41 -0700 Subject: [PATCH] [TCP]: Kill bogus comment above tcp_tso_acked(). Everything stated there is out of data. tcp_trim_skb() does adjust the available socket send buffer space and skb->truesize now. Signed-off-by: David S.
