That's indeed the WRITE SAME lookalike then. At least the SCSI people were smart enough to define an unmap bit for "hole punching" and allow the target to reject all other versions if they don't want to support it. Given that NFS v4.2 isn't finalized I'd very much recommend to a) properly separate those case s b) do not make the async version mandatory -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
