From 8732794b166196cc501c2ddd9e7c97cf45ab64c5 Mon Sep 17 00:00:00 2001 From: Wen Congyang Date: Tue, 11 Dec 2012 16:00:56 -0800 Subject: numa: convert static memory to dynamically allocated memory for per node device We use a static array to store struct node. In many cases, we don't have too many nodes, and some memory will be unused. Convert it to per-device dynamically allocated memory.
