But the idea of "randomizing" offsets on SSDs sounds like complete BS to start with. The whole job of the SSD is to remap from a random writable block device to difference physical blocks to deal with erases and wear leveling. In other words it really doesn't matter what offset your write to. That being said I could not actually find any code that does this randomization to start with, but that might just be my lack of grep skills.
