Subject: [RFC PATCH V2 0/3] block/dm: support bio polling
Date: Thu, 17 Jun 2021 18:35:46 +0800	[thread overview]
Message-ID: <20210617103549.930311-1-ming.lei@redhat.com> (raw)

Hello Guys,

Based on Christoph's bio based polling model[1], implement DM bio polling
with one very simple approach.

Patch 1 adds helper of blk_queue_poll().

Patch 2 adds .bio_poll() callback to block_device_operations, so bio
driver can implement its own logic for io polling.

Patch 3 implements bio polling for device mapper.

Any comments are welcome.

V2:
	- drop patch to add new fields into bio
	- support io polling for dm native bio splitting
	- add comment

Ming Lei (3):
  block: add helper of blk_queue_poll
  block: add ->poll_bio to block_device_operations
  dm: support bio polling
