I am sorry to be slow here but I am out of time right now - yeah having a lot of fun kaiser time. I didn't get to look at these patches at all yet but the changelog suggests that you want to remove vmem_altmap. I've had plans to (ab)use this for self hosted struct pages for memory hotplug http://lkml.kernel.org/r/20170801124111.28881-1-mhocko@kernel.org That work is stalled though because it is buggy and I was too busy to finish that work. Anyway, if you believe that removing vmem_altmap is a good step in general I will find another way. I wasn't really happy how the whole thing is grafted to the memory hotplug and (ab)used it only because it was handy and ready for reuse. Anyway if you need a review of mm parts from me, you will have to wait some more. If this requires some priority then go ahead and merge it. Times are just too crazy right now. Sorry about that. -- Michal Hocko SUSE Labs
