From 12462f1d9f0b96389497438dc2730c6f7410be82 Mon Sep 17 00:00:00 2001 From: Joel Becker Date: Wed, 3 Sep 2008 20:03:40 -0700 Subject: ocfs2: Add the 'inode64' mount option. Now that ocfs2 limits inode numbers to 32bits, add a mount option to disable the limit. This parallels XFS. 64bit systems can handle the larger inode numbers.
