| 5 | This determines which method will be used for unwinding kernel stack | |
| 6 | traces for panics, oopses, bugs, warnings, perf, /proc/<pid>/stack, | |
| 7 | lockdep, and more. | |

| 11 | help | |
| 12 | This option enables the "guess" unwinder for unwinding kernel stack | |
| 13 | traces. It scans the stack and reports every kernel text address it | |
| 14 | finds. Some of the addresses it reports may be incorrect. | |

| 16 | While this option often produces false positives, it can still be | |
| 17 | useful in many cases. | |

| 21 | depends on KALLSYMS | |
| 22 | help | |
| 23 | This option enables the "prologue" unwinder for unwinding kernel stack | |
| 24 | traces. It unwind the stack frame based on prologue code analyze. Symbol | |
| 25 | information is needed, at least the address and length of each function. | |
| 26 | Some of the addresses it reports may be incorrect (but better than the | |
| 27 | Guess unwinder). | |
