Re: [PATCH v7 06/15] s390/vfio-ap: Transition guest migration state from STOP to STOP_COPY

[sashiko-bot@kernel.org]

> The transition of the guest migration state from VFIO_DEVICE_STATE_STOP to
> VFIO_DEVICE_STATE_STOP_COPY begins the process of saving the
> vfio device state. The vfio device state is comprised of the guest's
> AP configuration which specifies the adapters, domains and control
> domains to which the guest will be given access.
> 
> To begin the process of saving the vfio device state, the VFIO AP device
> driver opens a file stream that will be used to read the source guest's
> AP configuration.
> 
> Note:
> This commit introduces the file operations structure for migration state
> files with a stub implementation of the read operation. The complete
> implementation is provided in the subsequent commit.
> 
> This incremental approach allows for easier review of the migration
> infrastructure setup separate from the actual implementation logic.
