4 #ifdef CONFIG_STACK_VALIDATION
6 * This macro marks the given function's stack frame as "non-standard", which
7 * tells objtool to ignore the function when doing stack metadata validation.
8 * It should only be used in special cases where you're 100% sure it won't
9 * affect the reliability of frame pointers and kernel stack traces.
11 * For more information, see tools/objtool/Documentation/stack-validation.txt.
