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.

Bart Van Assche (5):
  block: Declare several function pointer arguments 'const'
  block: Document the bio splitting functions
  block: Simplify bvec_split_segs()
  block: Simplify blk_bio_segment_split()
  block: Improve physical block alignment of split bios
