Led by Christoph Hellwig, the change expands protection coverage and gives file-systems like XFS direct knowledge of integrity errors. The new implementation also improves read performance by approximately 15% for 4K I/O and reduces QD1 latency for small I/O sizes. ## Full article daily.dev links to this article rather than hosting it.
