Hi, Rik. 

Actually, I tested this patch a few days ago.
I met problem like you that hang with udev.

I will debug it when I have a time. :)

BTW, last year I suggested that removing anon_vma facility itself in 
no swap machine(ie, embedded machine). 

Although your patch add small cost, many of small memory machine don't 
like it if they become to aware this patch.

So I want to make this patch configurable until we prove this patch is
no cost and afterwards we can remove configurable option.

Thanks for new trial to improve VM. :)
