My apologies for the last minute reviewing (I've been doing poor in processing
my backlog recently)!
The only question I have is about the relationship between NO_HOLE and
MAY_UNMAP, maybe you or Paolo can clarify that. Otherwise, the series looks
good. I've left a few other superficial questions to individual patches.
Thanks for the work!
