struct iomap_ioend currently tracks outstanding buffered writes and has some really nice code in core iomap and XFS to merge contiguous I/Os an defer them to userspace for completion in a very efficient way. For zoned writes we'll also need a per-bio user context completion to record the written blocks, and the infrastructure for that would look basically like the ioend handling for buffered I/O. So instead of reinventing the wheel, reuse the existing infrastructure.
