Can you explain your concerns?
Nothing really just yet. As I said, I need to get my head around Alex
code and figure before I take a position here. It might just be easier
for us to hook into the low level hash table invalidation code instead
and totally ignore the linux PTEs.
Are the hashes lazily or eagerly populated wrt the linux ptes?
Lazily.
In this case how can hooking the hashes work?
kvm obtains pages by calling get_user_pages_fast() so you can have a
page in the shadow hash which is not present in the host hash.
