Subject: [PATCH 0/2] Fix requests loss during virtio-blk device suspend
Date: Mon, 22 Jan 2024 19:07:20 +0800 [thread overview]
Message-ID: <20240122110722.690223-1-yi.sun@unisoc.com> (raw)
When a virtio-blk device performs a large number of IO operations and
requires sleep at the same time, some requests may never be successfully
processed.
It must be ensured that no requests in virtqueues before deleting.
The request becoming complete status means that the request has been removed
from the virtqueue.
Yi Sun (2):
blk-mq: introduce blk_mq_tagset_wait_request_completed()
virtio-blk: Ensure no requests in virtqueues before deleting vqs.
