From 53fc622b9e829c8e632e45ef8c14f054388759c1 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Thu, 20 Dec 2007 16:49:04 -0800 Subject: [PATCH 2/2] ocfs2: cluster aware flock() Hook up ocfs2_flock(), using the new flock lock type in dlmglue.c. A new mount option, "localflocks" is added so that users can revert to old functionality as need be.
