From ab3a1ffd11d90583c71bd606bf0fd5bfef30bce9 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 16 Dec 2016 15:11:05 -0500 Subject: [PATCH] radix tree test suite: Reduce kernel.h Many of the definitions in the radix-tree kernel.h are redundant with others in tools/include, or are no longer used, such as panic(). Move the definition of __init to init.h and in_interrupt() to preempt.h Signed-off-by: Matthew Wilcox --- tools/testing/radix-tree/linux/init.h | 2 +- tools/testing/radix-tree/linux/kernel.h | 39 +----------------------- tools/testing/radix-tree/linux/preempt.h | 10 ++++++ 3 files changed, 12 insertions(+), 39 deletions(-) diff --git a/tools/testing/radix-tree/linux/init.h b/tools/testing/radix-tree/linux/init.h index 360cabb3c4e7..1bb0afc21309 100644 --- a/tools/testing/radix-tree/linux/init.h +++ b/tools/testing/radix-tree/linux/init.h @@ -1 +1 @@ -/* An empty file stub that allows radix-tree.c to compile. */ +#define __init diff --git a/tools/testing/radix-tree/linux/kernel.h b/tools/testing/radix-tree/linux/kernel.h index 9681463c91e2..dd1d9aefb14f 100644 --- a/tools/testing/radix-tree/linux/kernel.h +++ b/tools/testing/radix-tree/linux/kernel.h @@ -1,10 +1,9 @@ #ifndef _KERNEL_H #define _KERNEL_H -#include +#include "../../include/linux/kernel.h" #include #include -#include #include #include @@ -19,47 +18,11 @@ #define RADIX_TREE_MAP_SHIFT 3 #endif -#ifndef NULL -#define NULL 0 -#endif - -#define BUG_ON(expr) assert(!(expr)) -#define __init -#define __must_check -#define panic(expr) #define printk printf -#define __force -#define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d)) #define pr_debug printk -#define smp_rmb() barrier() -#define smp_wmb() barrier() -#define cpu_relax() barrier() - #define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0])) -#define container_of(ptr, type, member) ({ \ - const typeof( ((type *)0)->member ) *__mptr = (ptr); \ - (type *)( (char *)__mptr - offsetof(type, member) );}) -#define min(a, b) ((a) < (b) ?
