 // Package uffd implements a userfaultfd-based memory server for Firecracker
 // snapshot restore. When a VM is restored from a snapshot, instead of loading
 // the entire memory file upfront, the UFFD handler intercepts page faults
 // and serves memory pages on demand from the snapshot's compact diff file.
