No, GFS1 is very much alive and current and probably will be for a long
time.  GFS1 will be available on RHEL5 (based on 2.6.18+) just as it was
on RHEL4.  That GFS1 code comes from the RHEL5 cvs branch in the cluster
tree.  If you're not using RHEL, GFS1 is also being maintained for recent
upstream kernels in the STABLE and HEAD cvs branches.

So, there are 4 versions of GFS1 that are currently being maintained:

cluster-infrastructure-v1 (cman-kernel):

1. RHEL4 kernels		(cvs RHEL4 branch, cluster/gfs-kernel)
2. recent upstream kernels	(cvs STABLE branch, cluster/gfs-kernel)

cluster-infrastructure-v2 (openais):

3. RHEL5 kernels		(cvs RHEL5 branch, cluster/gfs-kernel)
4. recent upstream kernels	(cvs HEAD, cluster/gfs-kernel)

We may decide to stop porting #2 forward after 2.6.20, but if others want
to send patches to continue it, we'd be happy to take them.
