The protection interval is not necessarily tied to the logical block size of a block device. Stop using the terms "sector" and "sectors". Going forward we will use the term "seed" to describe the initial reference tag value for a given I/O. "Interval" will be used to describe the portion of the data buffer that a given piece of protection information is associated with. Signed-off-by: Martin K.
