From abd1f50094cad9dff6d68ada98b495549f52fc30 Mon Sep 17 00:00:00 2001 From: Olaf Kirch Date: Wed, 4 Oct 2006 02:16:01 -0700 Subject: [PATCH] knfsd: lockd: optionally use hostnames for identifying peers This patch adds the nsm_use_hostnames sysctl and module param. If set, lockd will use the client's name (as given in the NLM arguments) to find the NSM handle. This makes recovery work when the NFS peer is multi-homed, and the reboot notification arrives from a different IP than the original lock calls.
