From c04fecb4d9f7753e0cbff7edd03ec68f8721cdce Mon Sep 17 00:00:00 2001 From: David Teigland Date: Thu, 10 May 2012 10:18:07 -0500 Subject: dlm: use rsbtbl as resource directory Remove the dir hash table (dirtbl), and use the rsb hash table (rsbtbl) as the resource directory. It has always been an unnecessary duplication of information. This improves efficiency by using a single rsbtbl lookup in many cases where both rsbtbl and dirtbl lookups were needed previously. This eliminates the need to handle cases of rsbtbl and dirtbl being out of sync. In many cases there will be memory savings because the dir hash table no longer exists.
