Subject: [PATCH v2 0/6] block-copy: use aio-task-pool
Date: Wed, 25 Mar 2020 16:46:33 +0300	[thread overview]
Message-ID: <20200325134639.16337-1-vsementsov@virtuozzo.com> (raw)

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
