Add a new module parameter 'pattern'. If it is set to zero, we will use the 55/AA pattern to torture the nand blocks; if it is set to a non-zero value, we will use the random data pattern.

Not a big issue in any way, but if you're using a numeric parameter value anyway, could not one use a range of the permissable values to set a seed for the random generation, so that the test can be repeated with the same set of random numbers?

Something like

0 => 55/AA
-1 => random
1 and up => random, specifying seed for random number generator.

+MODULE_PARM_DESC(pattern, "0 for 55/AA pattern(default), else for
+ the random pattern");

I'd suggest something like "0 for 55/AA pattern (default), non-zero for random pattern".

(Or "-1 for 55/AA pattern (default), else random; >=1 sets seed" if changed according to the above).
