Help text

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

While this option often produces false positives, it can still be useful in many cases. Unlike the other unwinders, it has no runtime overhead.
