#ifndef _LINUX_INIT_H
#define _LINUX_INIT_H
/* MODIFIED!!! */
/* These macros are used to mark some functions or
* initialized data (doesn't apply to uninitialized data)
* as `initialization' functions. The kernel can take this
* as hint that the function is used only during the initialization
* phase and free up used memory resources after
*
* Usage:
* For functions:
*
* You should add __init immediately before the function name, like:
*
* static void __init initme(int x, int y)
* {
* extern int z; z = x * y;
* }
*
* Depricated: you can surround the whole function declaration
* just before function body into __initfunc() macro, like:
*
* __initfunc (static void initme(int x, int y))
* {
* extern int z; z = x * y;
* }
*
* If the function has a prototype somewhere, you can also add
* __init between closing brace of the prototype and semicolon:
*
* extern int initialize_foobar_device(int, int, int) __init;
*
* For initialized data:
* You should insert __initdata between the variable name and equal
* sign followed by value, e.g.:
*
* static int init_variable __initdata = 0;
* static char linux_logo[] __initdata = { 0x32, 0x36, ... };
*
* For initialized data not at file scope, i.e. within a function,
* you should use __initlocaldata instead, due to a bug in GCC 2.7.
*/
/*
* Disable the __initfunc macros if a file that is a part of a
* module attempts to use them. We do not want to interfere
* with module linking.
