Ah is the issue the code duplication that Lorenzo has raised (ofcourse
completely agree that there is quite a bit), the lru.next patch I did
which hopefully [1] makes better, or investigating if it might be
interferring with DAX/VFIO that Lorenzo pointed out (will ofcourse
investigate before sending the next revision)? The mapcount work
(I think David is working on this?) that is needed to allow splitting
PUDs to PMD is completely a separate issue and can be tackled in parallel
to this.

I asked a couple of folks now and it seems they got it without any issue.
I have used it for a long time. I will try and see if something has changed.
