From 09e14305982efc2f3b509d3c50ef5dcbff64a998 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 3 May 2005 15:30:05 -0700 Subject: [NETLINK]: Fix infinite loops in synchronous netlink changes. The qlen should continue to decrement, even if we pop partially processed SKBs back onto the receive queue. Signed-off-by: David S.
