From bd1b1677b5d4f39deda068bf5cc43ce3aaec839f Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Mon, 25 Sep 2006 23:31:44 -0700 Subject: [PATCH] [PATCH] Guarantee that the uncached allocator gets pages on the correct node The uncached allocator manages per node pools. Specify __GFP_THISNODE in order to force allocation on the indicated node or fail. The uncached allocator has already logic to deal with failing allocations.
