These don't seem very important, to me. The APP_INSTANCE ones are
about clustered clients where VMs may want to migrate around the
cluster and not lose their VHDs. The OPEN_DEVICE_CONTEXT is about
MS-RSVD. Neither of these are in Linux?
The AAPL one is all about MacOS behaviors. If this is being added,
it needs additional documentation of the parameter block, no?
