Hi all!

This is the next step of improving block-copy: use aio task pool.

Async copying loop has better performance than linear, which is shown
in original series (was
"[RFC 00/24] backup performance: block_status + async", so this is
called v2)

Vladimir Sementsov-Ogievskiy (6):
  block/block-copy: rename in-flight requests to tasks
  block/block-copy: alloc task on each iteration
  block/block-copy: add state pointer to BlockCopyTask
  block/block-copy: move task size initial calculation to _task_create
  block/block-copy: move block_copy_task_create down
  block/block-copy: use aio-task-pool API
