7|---|---|---|
8| F_BLOB_PUT | hash, u64 job, u32 len, bytes | A push of the job's copy |
9| F_BLOB_ACK | hash, u32 ok, u64 job | The receiver's copy is durable (or was refused) |
10| F_BLOB_GET | hash, u64 job | A fetch: any job's copy serves |
11| F_BLOB | hash, u32 found, bytes | A fetch's answer |
