vhost: rename vhost_work_dev_flush

2022-05-31T16:45:10+00:00

This patch renames vhost_work_dev_flush to just vhost_dev_flush to relfect that it flushes everything on the device and that drivers don't know/care that polls are based on vhost_works. Drivers just flush the entire device and polls, and works for vhost-scsi management TMFs and IO net virtqueues, etc all are flushed.

vhost-test: drop flush after vhost_dev_cleanup

2022-05-31T16:45:10+00:00

The flush after vhost_dev_cleanup is not needed because: 1. It doesn't do anything. vhost_dev_cleanup will stop the worker thread so the flush call will just return since the worker has not device. 2. It's not needed. The comment about jobs re-queueing themselves does not look correct because handle_vq does not requeue work.

vhost_test: remove vhost_test_flush_vq()

2022-05-31T16:45:10+00:00

vhost_test_flush_vq() just a simple wrapper around vhost_work_dev_flush() which seems have no value. It's just easier to call vhost_work_dev_flush() directly. Besides there is no point in obtaining vhost_dev pointer via 'n->vqs[index].poll.dev' while we can just use &n->dev. It's the same pointers, see vhost_test_open()/vhost_dev_init().

vhost: get rid of vhost_poll_flush() wrapper

2022-05-31T16:45:10+00:00

vhost_poll_flush() is a simple wrapper around vhost_work_dev_flush(). It gives wrong impression that we are doing some work over vhost_poll, while in fact it flushes vhost_poll->dev. It only complicate understanding of the code and leads to mistakes like flushing the same vhost_dev several times in a row. Just remove vhost_poll_flush() and call vhost_work_dev_flush() directly.
