From ea9e4376bb545e400a325b3d76fecd02815303c0 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Wed, 28 Jul 2010 15:13:22 +1000 Subject: [PATCH] memblock: Improve debug output when resizing the reserve array Print out the location info in addition to which array is being resized. Also use memblocK_dbg() to put that under control of the memblock_debug flag.
