From 0188dc98ad5c7c361d46175623471d4be0fb8610 Mon Sep 17 00:00:00 2001 From: Oscar Salvador Date: Tue, 21 Aug 2018 21:53:39 -0700 Subject: mm/page_alloc: inline function to handle CONFIG_DEFERRED_STRUCT_PAGE_INIT Let us move the code between CONFIG_DEFERRED_STRUCT_PAGE_INIT to an inline function. Not having an ifdef in the function makes the code more readable.
