RE: [RFC PATCH 12/12] mm: let slab/slub/slob use mirrored memory

2015-06-04 Thread Luck, Tony 
-   page = alloc_pages_exact_node(nodeid, flags | __GFP_NOTRACK, 
cachep->gfporder);
+   page = alloc_pages_exact_node(nodeid, flags | __GFP_NOTRACK | 
__GFP_MIRROR,
+   cachep->gfporder);
 
Set some global "got_mirror"[*] if we have any mirrored memory to __GFP_MIRROR, 
else to 0.

then

page = alloc_pages_exact_node(nodeid, flags | __GFP_NOTRACK | 
got_mirror,
cachep->gfporder);
