Kent Overstreet, Bcachefs failure system developer, reported a 40% reduction in the number of pop-up errors when using the test toolkit compared to last month, as well as a significant decrease in the number of reports concerning critical issues. As a result of the work done, the overall code quality has improved, and the error flow has decreased. The Syzbot testing robot caught most of the trivial errors like 'oops, we forgot to check this' and now mainly finds truly rare and interesting situations.
Kent still knows several quite critical issues, such as the online fsck problem or problems with data structure packing (compaction), as well as issues with some tests hanging due to shortcomings in the write rate limiting code.
