Thanks for the info, Ray. Perhaps I'll find the time to pick up that
patch myself. Regarding the individual (numbered) comments that I made
there: I can clearly fix them up. But, the main problem I had with that
patch is that there was a sequence of hunks that were completely
impenetrable to me. I'm unsure if I could "untangle" those.
Anyway, as I said above, thanks for the info -- it's great to know that
you haven't abandoned that patch series, just have more pressing
developments to deal with.
Cheers!
Laszlo
