Reviving this thread a few months later...

Dave, we're interested in taking a serious look at what it would take to get
PMEM_IMMUTABLE working.  Do you still hold the opinion that this is (or could
become, with some amount of work) a workable solution?

We're happy to do the grunt work for this feature, but we will probably need
guidance from someone with more XFS experience.  With you out on extended leave
the first half of 2017, who would be the best person to ask for this guidance?
Darrick?

Thanks,
- Ross
