4/* These macros are used to mark some functions or
5 * initialized data (doesn't apply to uninitialized data)
6 * as `initialization' functions. The kernel can take this
7 * as hint that the function is used only during the initialization
8 * phase and free up used memory resources after
9 *
10 * Usage:
11 * For functions:
12 *
13 * You should add __init immediately before the function name, like:
14 *
15 * static void __init initme(int x, int y)
16 * {
17 * extern int z; z = x * y;
18 * }
19 *
20 * If the function has a prototype somewhere, you can also add
21 * __init between closing brace of the prototype and semicolon:
22 *
23 * extern int initialize_foobar_device(int, int, int) __init;
24 *
25 * For initialized data:
26 * You should insert __initdata between the variable name and equal
27 * sign followed by value, e.g.:
28 *
29 * static int init_variable __initdata = 0;
30 * static char linux_logo[] __initdata = { 0x32, 0x36, ... };
31 *
32 * Don't forget to initialize data not at file scope, i.e. within a function,
33 * as gcc otherwise puts the data into the bss section and not into the init
34 * section.
35 *
36 * Also note, that this data cannot be "const".

26 * For binary compatibility, 2.6 also supports the old "21", named

32 * PTRACE_OLDSETOPTIONS to to be the same as PTRACE_SETOPTIONS.
