From 899be4d3b7e00bf364d84c1c8cfe8bbbd1e3507b Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 30 Aug 2006 12:50:28 -0400 Subject: [PATCH] [GFS2] Add superblock into key for glock lookups This adds the superblock as a key for glock lookups. Since the glocks are already stored in a per-superblock table, this has no effect at the moment. Later on this will change though.
