[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
