The problems with C are real.

At the same time, the tooling has gotten much better in the last years.

Clang-analyzer is fast enough to run as part of the CI. Newer gcc also give quite a few more warnings for unused results.

My recommendation to the project is to

- Remove all compiler warnings and enable warning-as-error

- Increase the coverage of unit tests to >80%

That is a lot of work. But that's what is required for high-criticality systems engineering.

I hate to be the that OpenBSD guy, but "the people who do the work are the ones to decide how it's done". Yes, people are paid to maintain OpenZFS, but so far nobody is ready to pay for (or volunteer to) meet your bar.

Side note: OpenZFS already has an extensive test suite. Merely hitting a code branch wouldn't have caught this one.
