Subject: [PATCH v4 0/5] block-copy: use aio-task-pool
Date: Wed, 29 Apr 2020 16:08:42 +0300	[thread overview]
Message-ID: <20200429130847.28124-1-vsementsov@virtuozzo.com> (raw)

Hi all!

v4
01: add Max's r-b
04: move variable definition to the top of the block, add Max's r-b
05: - change error-codes in block_copy_task_run(), document them
      and be more accurate about error code in block_copy_dirty_clusters().
    - s/g_free(aio)/aio_task_pool_free(aio)/

==

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".

Vladimir Sementsov-Ogievskiy (5):
  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: refactor task creation
  block/block-copy: use aio-task-pool API
