Subject[PATCH 7/7] mm: page_alloc: Default allow file pages to use remote nodes for fair allocation policy
Date
Indications from Johannes that he wanted this. Needs some data and/or justification why
thrash protection needs it plus docs describing how MPOL_LOCAL is now different before
it should be considered finished. I do not necessarily agree this patch is necessary
but it's worth punting it out there for discussion and testing.
