The question is what is the minimum value for submitting upstream...
The thing pnfs over dlm/gfs2 is missing mostly is supporting read/write layout.
One could use them load balancing, e.g. by either redirecting to a node
holding an exclusive lock on the file, if there is one, or dlm_ino_hash in its absence.
One could do a lot of things, especially given infinite time. But what
does the current code buy us? We need data on that to justify merging
such a large chunk of code.
I think that we can help figure out how to get something reasonably useful ready
for upstream, just need to get some people spun up to help test out some of
these ideas...
