Well, when is this code called? It would be at boot time, in which case
the allocations will succeed (if not, the boot fails) or at cpu/node
hot-add, in which case the appropriate response is to fail to bring up the
new cpu/node.
It's better to send the administrator back to work out why we ran out of
memory than to appear to have brought the new cpu/node online, only to have
it run funny.
I think?
I agree, for bootup/hot-add.
Not so sure about exclusive cpusets.
