Subject: [PATCH v2 0/2] virtio-blk: set req->state to MQ_RQ_COMPLETE and support completion batching for the IRQ path
Date: Wed, 21 Dec 2022 00:36:11 +0900 [thread overview]
Message-ID: <20221220153613.21675-1-suwan.kim027@gmail.com> (raw)
V2 changes
- patch#1
- use blk_mq_complete_request_remote() instead of blk_mq_set_request_complete()
- patch#2
- Modify patch based on the patch#1 v2 changes.
- Use iob.complete(&iob) instead of virtblk_complete_batch(&iob)
at virtblk_done() (Stefan's comment)
- It shows almost same performance improvement as v1 patch.
