Some allocations done by KVM are temporary, they are created as result of program actions, but can't exists for arbitrary long times. They should have been GFP_TEMPORARY (rip!). OTOH, kvm-nx-lpage-recovery and kvm-pit kernel threads exist for as long as VM exists but their task_struct memory is not accounted. This is story for another day.
