Gang He reports the failure of building fs/ocfs2/ as an external module
of the kernel installed on the system:
$ cd fs/ocfs2
$ make -C /lib/modules/`uname -r`/build M=`pwd` modules
If you want to make it work reliably, I'd recommend to remove ccflags-y
from the Makefiles, and to make header paths relative to the C files. I
think this is the correct usage of the #include "..." directive.

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.

Rather than directly using o2dlm, dlmfs can now use the stackglue. This
allows it to use userspace cluster stacks and fs/dlm. This commit
forces o2cb for now. A latter commit will bump the protocol version and
allow non-o2cb stacks.
This is one big sed, really. LKM_xxMODE becomes DLM_LOCK_xx. LKM_flag
becomes DLM_LKF_flag.
We also learn to check that the LVB is valid before reading it. Any DLM
can lose the contents of the LVB during a complicated recovery. userdlm
should be checking this. Now it does. dlmfs will return 0 from read(2)
if the LVB was invalid.

We're going to remove the tie between ocfs2_dlmfs and o2dlm.
ocfs2_dlmfs doesn't belong in the fs/ocfs2/dlm directory anymore. Here
we move it to fs/ocfs2/dlmfs.
