I'll need to study the Hyper-V code and how it's done today - I guess most part of this implementation will be studying the notifiers we have currently, split them among the 3 new notifiers and comb them into patches, so they can be reviewed for all relevant maintainers (who know the code we are changing). I'm not sure if I go directly with the draft, likely it'll have some changes, but the draft should be the skeleton of the new implementation. Specially if you/other kdump maintainers agree it's a good idea =) Cheers, Guilherme
