From 37a034729ae611295bbb8e925333d4d54d7c1ebc Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 4 Oct 2006 02:15:44 -0700 Subject: [PATCH] knfsd: call lockd_down when closing a socket via a write to nfsd/portlist The refcount that nfsd holds on lockd is based on the number of open sockets. So when we close a socket, we should decrement the ref (with lockd_down). Currently when a socket is closed via writing to the portlist file, that doesn't happen. So: make sure we get an error return if the socket that was requested does is not found, and call lockd_down if it was. Cc: "J.
