Commit c271c5c2 authored by Sunil Mushran's avatar Sunil Mushran Committed by Mark Fasheh

ocfs2: local mounts

This allows users to format an ocfs2 file system with a special flag,
OCFS2_FEATURE_INCOMPAT_LOCAL_MOUNT. When the file system sees this flag, it
will not use any cluster services, nor will it require a cluster
configuration, thus acting like a 'local' file system.
