From e7fd41792fc0ee52a05fcaac87511f118328d147 Mon Sep 17 00:00:00 2001 From: David Teigland Date: Wed, 18 Jan 2006 09:30:29 +0000 Subject: [DLM] The core of the DLM for GFS2/CLVM This is the core of the distributed lock manager which is required to use GFS2 as a cluster filesystem. It is also used by CLVM and can be used as a standalone lock manager independantly of either of these two projects. It implements VAX-style locking modes.
