Thanks kevin and Bob for the information.
When can we expect GFS2 for production?

subject Re: [Linux-cluster] GFS vs. GFS2: system-config-cluster, locking ...
FYI--For 5.x, the locking infrastructure was common between GFS
and GFS2. It has to do with the common lock harness "lock_dlm"
that is an interface between both GFS and GFS2 into the "dlm" module.
For 5.3, we're splitting the locking modules apart to get rid of
that dependency.
