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. [ Added description of inode64 mount option in ocfs2.txt. --Mark ] Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
