Sure, aprecciated the time ;-)
One thing to look into right now is how to make this fly this with vmemmap
optimizations for hugetlb pages.

I was about to have a look at that series eitherway, but good you mentioned.
More eyes on that series would be appreciated.
That series will dynamically free and allocate memmap pages as hugetlb
pages are allocated or freed. I haven't looked through this series, but
my first thought is that we would need to ensure those allocs/frees are
directed to the device. Not sure if there are interfaces for that.
