Achieving end-to-end data integrity is essential for modern storage systems, yet Linux still faces challenges in providing full-stack protection. This session explores recent improvements in Linux’s data integrity framework. Specifically this presentation shares detail about:

1. A new io_uring interface that enables applications to attach metadata with I/O requests, ensuring robust data protection.

2. Optimizations to existing integrity mechanisms that improve performance, reduce overhead, and enhance flexibility, all of which have been merged into the mainline kernel.

3. Lastly, we highlight a novel mechanism that allows filesystems to fully utilize device integrity features and helps optimizing host and device resource utilization.

This presentation will deliver in-depth technical insights into these advancements and their role in strengthening Linux storage reliability.
