The article is not about which filesystem to use or not, but about the size and contents of the patches submitted in relation to bcachefs. It seems that the submitted changes which should have been just fixes also contain new functionality. Though it is very nice to see how active and enthusiastic the development of bcachefs is, mixing fixes with new functionality is hard to review and dangerous as it can introduce additional issues. Again, while I appreciate Kents work, I understand Linus’ concerns.
