From 66e8b438bd5c75498cfe915c4219049eaebcb869 Mon Sep 17 00:00:00 2001 From: Gioh Kim Date: Wed, 15 Nov 2017 17:33:42 -0800 Subject: mm/memblock.c: make the index explicit argument of for_each_memblock_type for_each_memblock_type macro function relies on idx variable defined in the caller context. Silent macro arguments are almost always wrong thing to do. They make code harder to read and easier to get wrong. Let's use an explicit iterator parameter for for_each_memblock_type and make the code more obious. This patch is a mere cleanup and it shouldn't introduce any functional change.
