From 4e2fd495b520b51e4ba83340f13520b7f07e3743 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 10 Apr 2006 22:55:39 -0700 Subject: [PATCH] [PATCH] knfsd: nfsd4: add missing rpciod_down() We should be shutting down rpciod for the callback channel when we shut down the server. Also note that we do rpciod_up() and create the callback client *before* setting cb_set--the cb_set only determines whether the initial null was succesful. So cb_set is not a reliable determiner of whether we need to clean up, only cb_client is. Signed-off-by: J.
