Sorry for replying to myself.

Actually, I will take one more try at this - when I first looked at Hongo Li's 
patches
to do the conversion, it seemed like there were a few problems, and I didn't 
review
fully. I realize now that although it was a different approach than I had been 
taking,
perhaps it was on the right track after all.

I'll try to evaluate that patch series more carefully and see if it solved the 
problems
I am struggling with now.

If it does, I'd be happy to work with you, Hongbo, to get this completed. Your 
series
will take a bit of forward-porting, as the codebase has moved forward quite a 
lot
since then. But I'll go back to an older kernel and evaluate the net result of 
your
changes, since I have some custom mount-option-testing framework here, and see 
how
things look.

Thanks,
-Eric
