Hi Jens, This patch series improves bio splitting in several ways: - Reduce the number of CPU cycles spent in bio splitting code. - Make the bio splittig code easier to read. - Optimize alignment of split bios. Please consider this patch series for kernel v5.4. Thanks, Bart. Changes compared to v1: addressed Johannes' review feedback.
