| 6 | /* These macros are used to mark some functions or |
||
| 7 | * initialized data (doesn't apply to uninitialized data) |
||
| 8 | * as `initialization' functions. The kernel can take this |
||
| 9 | * as hint that the function is used only during the initialization |
||
| 10 | * phase and free up used memory resources after |
||
| 11 | * |
||
| 12 | * Usage: |
||
| 13 | * For functions: |
||
| 14 | * |
||
| 15 | * You should add __init immediately before the function name, like: |
||
| 16 | * |
||
| 17 | * static void __init initme(int x, int y) |
||
| 18 | * { |
||
| 19 | * extern int z; z = x * y; |
||
| 20 | * } |
||
| 21 | * |
||
| 22 | * Depricated: you can surround the whole function declaration |
||
| 23 | * just before function body into __initfunc() macro, like: |
||
| 24 | * |
||
| 25 | * __initfunc (static void initme(int x, int y)) |
||
| 26 | * { |
||
| 27 | * extern int z; z = x * y; |
||
| 28 | * } |
||
| 29 | * |
||
| 30 | * If the function has a prototype somewhere, you can also add |
||
| 31 | * __init between closing brace of the prototype and semicolon: |
||
| 32 | * |
||
| 33 | * extern int initialize_foobar_device(int, int, int) __init; |
||
| 34 | * |
||
| 35 | * For initialized data: |
||
| 36 | * You should insert __initdata between the variable name and equal |
||
| 37 | * sign followed by value, e.g.: |
||
| 38 | * |
||
| 39 | * static int init_variable __initdata = 0; |
||
| 40 | * static char linux_logo[] __initdata = { 0x32, 0x36, ... }; |
||
| 41 | * |
||
| 42 | * For initialized data not at file scope, i.e. within a function, |
||
| 43 | * you should use __initlocaldata instead, due to a bug in GCC 2.7. |
||
| 44 | */ |
||
| 45 | |||
| 46 | /* |
||
| 47 | * Disable the __initfunc macros if a file that is a part of a |
||
| 48 | * module attempts to use them. We do not want to interfere |
||
| 49 | * with module linking. |
