I am not terribly surprised to learn that code review processes for the kernel are not as stringent as they should be. However, I do wonder whether the kernel's defect rate is significantly different from that of NT or XNU, and whether the situation could be significantly improved. I thought there was large institutional investment in Linux kernel development, but if the existing developers are horribly overworked and stand no chance of properly reviewing every patch, even from existing contributors, clearly the project needs more resources. I'm glad that this situation has prompted reflection on these issues for kernel developers though. It seems like the best possible outcome.
