Subject: [PATCH v2 0/3] Improve virtio-blk performance

This patchset implements bio-based IO path for virito-blk to improve
performance.

Fio test shows it gives, 28%, 24%, 21%, 16% IOPS boost and 32%, 17%, 21%, 16%
latency improvement for sequential read/write, random read/write respectively.

Asias He (3):
  block: Introduce __blk_segment_map_sg() helper
  block: Add blk_bio_map_sg() helper
  virtio-blk: Add bio-based IO path for virtio-blk
