From 6b54dae2b0defb30babb0fe87b13463b9f4b2907 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 4 Oct 2006 02:16:15 -0700 Subject: [PATCH] [PATCH] knfsd: lockd: fix refount on nsm If nlm_lookup_host finds what it is looking for it exits with an extra reference on the matching 'nsm' structure. So don't actually count the reference until we are (fairly) sure it is going to be used.
