    block: add support for limiting gaps in SG lists · 66cb45aa
    Jens Axboe 提交于
    Another restriction inherited for NVMe - those devices don't support
    SG lists that have "gaps" in them. Gaps refers to cases where the
    previous SG entry doesn't end on a page boundary. For NVMe, all SG
    entries must start at offset 0 (except the first) and end on a page
    boundary (except the last).
