From 380b6549e5f799fabc5523a09446aa8c4da8c26b Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sun, 11 Oct 2015 15:47:32 -0400 Subject: [PATCH] drivers/staging: make android lowmemorykiller.c explicitly non-modular MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Kconfig currently controlling compilation of this code is: drivers/staging/android/Kconfig:config ANDROID_LOW_MEMORY_KILLER drivers/staging/android/Kconfig: bool "Android Low Memory Killer" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We replace module.h with init.h and moduleparam.h ; the latter since this file was previously implicitly relying on getting that header. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
