Subject: [PATCH] TCP : use LIMIT_NETDEBUG in tcp_retransmit_timer()
Date: Mon, 04 Jun 2007 09:13:40 +0200 [thread overview]
Message-ID: <4663BBA4.70009@cosmosbay.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 220 bytes --]
LIMIT_NETDEBUG allows the admin to disable some warning messages (echo 0
>/proc/sys/net/core/warnings).
The "TCP: Treason uncloaked!" message can use this facility.
