From 692ae74aaf226a557d88d5412a1764c09e63a193 Mon Sep 17 00:00:00 2001 From: Byongho Lee Date: Wed, 31 Jan 2018 16:15:36 -0800 Subject: mm/slab_common.c: make calculate_alignment() static calculate_alignment() function is only used inside slab_common.c. So make it static and let the compiler do more optimizations. After this patch there's a small improvement in text and data size. $ gcc --version gcc (GCC) 7.2.1 20171128 Before: text data bss dec hex filename 9890457 3828702 1212364 14931523 e3d643 vmlinux After: text data bss dec hex filename 9890437 3828670 1212364 14931471 e3d60f vmlinux Also I fixed a style problem reported by checkpatch.
