Switch to using our internal Tausworthe based random generator for offsets It's both faster and more exhaustive than what is available on glibc on my test systems. So no downsides, and the upside of having the same offset generator across all platforms. This will change the random series, so could alter performance for your workload since the pattern will be different in sequence. There's an option to revert to the OS generator, you can add use_us_rand=1 on your job files to retain the old generator offsets. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

When verify fails, dump the good/bad blocks to files This makes it easy to compare afterwards to see what kind of corruption was experienced. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
