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. 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() arch/um/drivers/virtio_uml.c | 33 ++--- drivers/platform/mellanox/mlxbf-tmfifo.c | 25 ++-- drivers/remoteproc/remoteproc_virtio.c | 34 ++--- drivers/s390/virtio/virtio_ccw.c | 35 ++--- drivers/virtio/virtio_balloon.c | 46 +++--- drivers/virtio/virtio_mmio.c | 33 ++--- drivers/virtio/virtio_pci_common.c | 62 +++----- drivers/virtio/virtio_pci_common.h | 9 +- drivers/virtio/virtio_pci_legacy.c | 16 ++- drivers/virtio/virtio_pci_modern.c | 37 +++-- drivers/virtio/virtio_ring.c | 173 ++++++++--------------- drivers/virtio/virtio_vdpa.c | 48 +++---- include/linux/virtio_config.h | 75 +++++++--- include/linux/virtio_ring.h | 93 +++++++----- tools/virtio/virtio_test.c | 4 +- tools/virtio/vringh_test.c | 28 ++-- 16 files changed, 350 insertions(+), 401 deletions(-) --- 2.32.0.3.g01195cf9f
