[Ocfs2-devel] [PATCH 0/6] nocontrold: Eliminating ocfs2_controld

[Mark Fasheh]

Firstly, thanks for developing this Goldwyn. I've been looking at the
patches, and plan to review the series (in kernel) for you.

Quick question - do you have a pointer handy to the development stream on
the dlm / gfs side of things? It would be instructive to see how it was done
in more than one place.
