[PATCH 4/8] Preserve original node for transparent huge page copies

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

This makes a difference for LOCAL policy, where the node cannot
be determined from the policy itself, but has to be gotten
from the original page.
