ocfs2_dlmfs: Enable the use of user cluster stacks.
Unlike ocfs2, dlmfs has no permanent storage. It can't store off a cluster stack it is supposed to be using. So it can't specify the stack name in ocfs2_cluster_connect(). Instead, we create ocfs2_cluster_connect_agnostic(), which simply uses the stack that is currently enabled. This is find for dlmfs, which will rely on the stack initialization. We add the "stackglue" capability to dlmfs's capability list. This lets userspace know dlmfs can be used with all cluster stacks. Signed-off-by: Joel Becker <joel.becker@oracle.com>
