The kernel doesn't have any kind of coherent testing strategy. That was a big part of the problem, because that means the subsystems that do test their code, like bcachefs, get stuck picking up the slack for the subsystems that don't.

I was spending a lot of my time just doing QA for the rest of the kernel.

You seem to just be painfully misinformed - or you're outright trolling.
