Hi John, Along with rtvol check, we can also have a simple check to see if the FS blocksize itself is big enough to satisfy the atomic requirements. For eg on machines with 64K page, we can have say 16k or 64k block sizes which should be able to provide required allocation behavior for atomic writes. In such cases we don't need rtvol.
