kvm, mm: account kvm related kmem slabs to kmemcg
[ Upstream commit 46bea48ac241fe0b413805952dda74dd0c09ba8b ]
The kvm slabs can consume a significant amount of system memory
and indeed in our production environment we have observed that
a lot of machines are spending significant amount of memory that
can not be left as system memory overhead. Also the allocations
from these slabs can be triggered directly by user space applications
which has access to kvm and thus a buggy application can leak
such memory. So, these caches should be accounted to kmemcg.
