Can you explain how you expect this to be called by a file system? We've debated this in the past and concluded that we probably want to do it at the same time as batched discard, but I don't see if the sanitize request should be sent for each FITRIM or whether we should better have a separate file system level ioctl. My feeling is that it would be more useful to call this feature through a file system level ioctl than through a block level ioctl, but I guess it makes sense to support both.
