From 6a4055bc72a516bae3f607eda3e243d18e66bd49 Mon Sep 17 00:00:00 2001 From: Alexander Kuleshov Date: Wed, 15 Apr 2015 16:14:44 -0700 Subject: mm/memblock.c: add debug output for memblock_add() memblock_reserve() calls memblock_reserve_region() which prints debugging information if 'memblock=debug' was passed on the command line. This patch adds the same behaviour, but for memblock_add function().
