Re: [PATCH v10 05/15] s390/vfio-ap: Callback to get/set vfio device mig state during guest migration

[sashiko-bot@kernel.org]

> Implements two callbacks related to the current state of a vfio-ap device:
> * The callback that sets a new migration state of a vfio-ap device during
>   live migration of guests with pass-through access to AP devices. This
>   callback is mandatory for VFIO_DEVICE_FEATURE_MIGRATION support.
> 
>   The function pointer for this callback is specified via the
>   'migration_set_state' field of the 'vfio_migration_ops' structure
>   which is stored with the VFIO device when the 'vfio_device'
>   structure representing the mediated device is initialized.
> 
> * The callback that returns the current vfio device migration state during
>   live migration of guests with pass-through access to AP devices.
> 
>   The function pointer for this callback is specified via the
>   'migration_get_state' field of the 'vfio_migration_ops' structure
>   which is stored with the VFIO device when the 'vfio_device'
