[PATCH 0/6] block-copy: memory limit

Posted by Vladimir Sementsov-Ogievskiy 4 years, 6 months ago

Hi all!

I'm going to bring block-status driven, async copying process to
block-copy, to make it fast. The first step is to limit memory usage of
backup, here is it.

Based on my "[PATCH v15 0/5] backup-top filter driver for backup":
Based-on: <20191001131409.14202-1-vsementsov@virtuozzo.com>

Vladimir Sementsov-Ogievskiy (6):
  block/block-copy: allocate buffer in block_copy_with_bounce_buffer
  block/block-copy: limit copy_range_size to 16 MiB
  block/block-copy: refactor copying
  util: introduce co-shared-amount
  block/block-copy: add memory limit
  block/block-copy: increase buffered copy request
