...le plug in more memory - usually
because the existing memory isn't enough, which implies that the free
page list is very likely to be close to empty.
- This method could be easily scaled if people really need more headroom
for hot-plugged memory. For example, calculation based on "X *
total_ram_pages", X could be a number passed from the hypervisor.
- This is an optimization feature, and reporting less free memory in
that rare case doesn't hurt anything.
So I think it is good to start from a fundamental implementation, which
doesn't confuse people, and complexities can be add...
