From 14298d3663e44705d3f9106343ac8298a5fdff99 Mon Sep 17 00:00:00 2001 From: Dou Liyang Date: Thu, 5 Apr 2018 16:23:53 -0700 Subject: [PATCH] mm/page_poison.c: make early_page_poison_param() __init The early_param() is only called during kernel initialization, So Linux marks the function of it with __init macro to save memory. But it forgot to mark the early_page_poison_param(). So, Make it __init as well.
