From 6714d8e86bf443f6f7af50f9d432025649f091f5 Mon Sep 17 00:00:00 2001 From: Kurt Hackel Date: Thu, 15 Dec 2005 14:31:23 -0800 Subject: [PATCH] OCFS2: The Second Oracle Cluster Filesystem A distributed lock manager built with the cluster file system use case in mind. The OCFS2 dlm exposes a VMS style API, though things have been simplified internally. The only lock levels implemented currently are NLMODE, PRMODE and EXMODE.
