| # Returns `0` if `module.ko` is a Rust module, `1` otherwise. |
| # Using the `16_` prefix ensures other symbols with the same substring |
| # are not picked up (even if it would be unlikely). The last part is |
| # used just in case LLVM decides to use the `.` suffix. |
| # In the future, checking for the `.comment` section may be another |
| # option, see https://github.com/rust-lang/rust/pull/97550. |
