[PATCH] MAINTAINERS: add missing virtio/vdpa/vduse/vhost headers

[PATCH] MAINTAINERS: add missing virtio/vdpa/vduse/vhost headers

[Eugenio Pérez]

Several headers related to virtio, vDPA, VDUSE and vhost were not
covered by any specific MAINTAINERS entry and fell through to the
catch-all THE REST section:

- include/linux/device-id/virtio.h: not matched by the existing
  "include/linux/virtio*.h" glob, which only matches files directly
  under include/linux/ and does not recurse into subdirectories.

- include/uapi/linux/vdpa.h: the in-kernel include/linux/vdpa.h was
  listed under VIRTIO CORE but its UAPI companion was missing; the
  "include/uapi/linux/virtio_*.h" pattern does not match it because
  the filename lacks the "virtio_" prefix.

- include/uapi/linux/vduse.h: there is no dedicated VDUSE section in
  MAINTAINERS; the driver lives under drivers/vdpa/ which is already
  covered by VIRTIO CORE, so the UAPI header belongs there too.

- include/uapi/linux/vhost_types.h: the VIRTIO HOST (VHOST) section
  explicitly lists include/uapi/linux/vhost.h but omits its companion
  types header.

I forgot:
Suggested-by: Michael S. Tsirkin <mst@redhat.com>

Also, in case it is useful, the model looked for all the potentially
missed files.

Maybe we should tell to the agent to avoid useless info in the commit 
message, I mean it's pretty clear that "include/uapi/linux/virtio_*.h" 
will not match include/uapi/linux/vdpa.h ...

nit: the suggested tag in Documentation/process/coding-assistants.rst is

Anyway, the patch LGTM:

Reviewed-by: Stefano Garzarella <sgarzare@redhat.com>


Maybe to be fixed in another patch, LLM here found also others files 
related to virtio/vhost/vdpa uncovered:

Other virtio-related files not covered by any virtio/vhost/vdpa
MAINTAINERS entry:

- Documentation/ABI/testing/sysfs-fs-virtiofs
   Current:   no section (THE REST only)
   Suggested: VIRTIO FILE SYSTEM

- Documentation/userspace-api/vduse.rst
   Current:   DOCUMENTATION only
   Suggested: VIRTIO CORE (already lists sysfs-class-vduse)

- include/trace/events/vsock_virtio_transport_common.h
   Current:   TRACING only
   Suggested: VIRTIO AND VHOST VSOCK DRIVER
              (next to virtio_transport_common.c)

- drivers/nvdimm/virtio_pmem.h
   Current:   LIBNVDIMM only
   Suggested: VIRTIO PMEM DRIVER (lists virtio_pmem.c and
              nd_virtio.c, but not the header)

- Documentation/devicetree/bindings/gpio/gpio-virtio.yaml
   Current:   GPIO + DT bindings
   Suggested: VIRTIO GPIO DRIVER

- Documentation/devicetree/bindings/i2c/i2c-virtio.yaml
   Current:   I2C + DT bindings
   Suggested: VIRTIO I2C DRIVER

- Documentation/networking/device_drivers/ethernet/amd/pds_vdpa.rst
   Current:   NETWORKING + DOCUMENTATION
   Suggested: PDS DSC VIRTIO DATA PATH ACCELERATOR
              (only lists drivers/vdpa/pds/)

- include/linux/mlx5/mlx5_ifc_vdpa.h
   Current:   MLX5 core/IB only
   Suggested: possibly MELLANOX MLX5 VDPA DRIVER (debatable, it's an
              mlx5 interface header)


I'll send a fix for the vsock events.

Thanks,
Stefano
