[PATCH v2 for-5.0 0/7] block-copy improvements: part I

[Vladimir Sementsov-Ogievskiy]

Hi all!

This is a first part of my
  [RFC 00/24] backup performance: block_status + async

Patches are mostly separate by their idea, but sending them all in
separate is inefficient.

Vladimir Sementsov-Ogievskiy (7):
  block/block-copy: specialcase first copy_range request
  block/block-copy: use block_status
  block/block-copy: factor out block_copy_find_inflight_req
  block/block-copy: refactor interfaces to use bytes instead of end
  block/block-copy: rename start to offset in interfaces
  block/block-copy: reduce intersecting request lock
  block/block-copy: hide structure definitions
