From 8818a9d884e3a589899be3303958fff182e98e55 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ilpo=20J=C3=A4rvinen?= Date: Wed, 2 Dec 2009 22:24:02 -0800 Subject: [PATCH] tcp: clear hints to avoid a stale one (nfs only affected?) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Eric Dumazet mentioned in a context of another problem: "Well, it seems NFS reuses its socket, so maybe we miss some cleaning as spotted in this old patch" I've not check under which conditions that actually happens but if true, we need to make sure we don't accidently leave stale hints behind when the write queue had to be purged (whether reusing with NFS can actually happen if purging took place is something I'm not sure of). ...At least it compiles.
