@@ -505,6 +505,11 @@ bs_unaligned       If this option is given, any byte size value within bsrange
                may be used as a block range. This typically wont work with
                direct IO, as that normally requires sector alignment.
 
+bs_is_seq_rand If this option is set, fio will use the normal read,write
+               blocksize settings as sequential,random instead. Any random
+               read or write will use the WRITE blocksize settings, and any
+               sequential read or write will use the READ blocksize setting.

 zero_buffers   If this option is given, fio will init the IO buffers to
                all zeroes. The default is to fill them with random data.
