You could return a read-only grant to found data, because those grants have byte-granularity.

And a filesystem daemon could also provide shared mmaped files in the direct VM space (instead of process-specific VM space).—hmm that wouldn’t work. How can IPC use the same parameters both when passing by copy and through zero-copy (VM manipulation)?
