Subject: [PATCH vhost v6 0/6] refactor the params of find_vqs()
Date: Wed, 27 Mar 2024 17:57:35 +0800	[thread overview]
Message-ID: <20240327095741.88135-1-xuanzhuo@linux.alibaba.com> (raw)

This pathset is splited from the

     http://lore.kernel.org/all/20240229072044.77388-1-xuanzhuo@linux.alibaba.com

That may needs some cycles to discuss. But that notifies too many people.

But just the four commits need to notify so many people.
And four commits are independent. So I split that patch set,
let us review these first.

The patch set try to  refactor the params of find_vqs().
Then we can just change the structure, when introducing new
features.

Thanks.

v6:
  1. virtio_balloon: a single variable for both purposes.
  2. if names[i] is null, return error

v5:
  1. virtio_balloon: follow David Hildenbrand's suggest
    http://lore.kernel.org/all/3620be9c-e288-4ff2-a7be-1fcf806e6e6e@redhat.com
  2. fix bug of the reference of "cfg_idx"
    http://lore.kernel.org/all/202403222227.Sdp23Lcb-lkp@intel.com

v4:
  1. remove support for names array entries being null
  2. remove cfg_idx from virtio_vq_config

v3:
  1. fix the bug: "assignment of read-only location '*cfg.names'"

v2:
  1. add kerneldoc for "struct vq_transport_config" @ilpo.jarvinen

v1:
  1. fix some comments from ilpo.jarvinen@linux.intel.com

Xuan Zhuo (6):
  virtio_balloon: remove the dependence where names[] is null
  virtio: remove support for names array entries being null.
  virtio: find_vqs: pass struct instead of multi parameters
  virtio: vring_create_virtqueue: pass struct instead of multi
    parameters
  virtio: vring_new_virtqueue(): pass struct instead of multi parameters
  virtio_ring: simplify the parameters of the funcs related to
    vring_create/new_virtqueue()
