From b03efcfb2180289718991bb984044ce6c5b7d1b0 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 8 Jul 2005 14:57:23 -0700 Subject: [NET]: Transform skb_queue_len() binary tests into skb_queue_empty() This is part of the grand scheme to eliminate the qlen member of skb_queue_head, and subsequently remove the 'list' member of sk_buff. Most users of skb_queue_len() want to know if the queue is empty or not, and that's trivially done with skb_queue_empty() which doesn't use the skb_queue_head->qlen member and instead uses the queue list emptyness as the test.
