From 248f06726e866942b3d8ca8f411f9067713b7ff8 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 2 Mar 2007 12:49:23 -0800 Subject: [PATCH] [AF_UNIX]: Test against sk_max_ack_backlog properly. This brings things inline with the sk_acceptq_is_full() bug fix. The limit test should be x >= sk_max_ack_backlog. Signed-off-by: David S.
