Big patchset.  I'll await some reviewer input before looking at merging
this, I think.

Please update Documentation/filesystems/ocfs2.txt to document all the
new userspace interfaces and the overall feature, etc.

Should the new code be hidden behind `#ifdef CONFIG_IPV6'?  That would
avoid some code bloat.

(That being said, if ocfs2 was concerned about code bloat, it would do
something about the fact that mlog() and mlog_errno() more than double
the file system's object code size).
