So quite frankly, I don't like how this was done.
When you touch files like mm/memory.c, you don't just touch them. You
get sign-offs and acks from the VM maintainers. Seriously.
In this case, I pulled, looked, and then unpulled. I just don't want
it, and I think the new FAULT_FLAG_MINOR is seriously mis-named and
hacky.
Is it about atomicity? Is it about IO? Why wasn't I notified
before-hand? Was Andrew cc'd?
Not pulled.
