- * In 1.6 and 1.8 the checksum was computed only on struct ptlrpc_body as
- * it was in 1.6 (88 bytes, smaller than the full size in 1.8).  It makes
- * more sense to compute the checksum on the full ptlrpc_body, regardless
- * of what size it is, but in order to keep interoperability with 1.8 we
- * can optionally also checksum only the first 88 bytes (caller decides). */
