The problem is that there are some devices that may return errors in response to a discard request some times but not others. (One example would be a hybrid dm device which concatenates an SSD and an HDD device). By this logic, I also removed the error checking from ext4's FITRIM code; so that an error from a discard will not stop the FITRIM from trying to trim the rest of the file system.
