3/// DeviceSubRequest describes a request for device provided in the claim.spec.devices.requests\[\].firstAvailable array. Each is typically a request for a single resource like a device, but can also ask for several identical devices.
4///
5/// DeviceSubRequest is similar to Request, but doesn't expose the AdminAccess or FirstAvailable fields, as those can only be set on the top-level request. AdminAccess is not supported for requests with a prioritized list, and recursive FirstAvailable fields are not supported.

The scheduler will not let new pods reserve the claim while it has these tainted devices.
