From cab0a7c115546a4865fb7439558af9077a569574 Mon Sep 17 00:00:00 2001 From: Ting Liu Date: Fri, 14 Jan 2022 14:09:28 -0800 Subject: mm: make some vars and functions static or __init "page_idle_ops" as a global var, but its scope of use within this document. So it should be static. "page_ext_ops" is a var used in the kernel initial phase. And other functions are aslo used in the kernel initial phase. So they should be __init or __initdata to reclaim memory.
