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! Fam
