The eject command from the util-linux package does not work with the swim3 driver: the drive doesn't eject anything and the command fails. Apparently, ioctl(fd, FDEJECT) returns -EBUSY after fd was opened O_EXCL. Fix this by checking ref_count for either 1 or -1. Either value means that the caller is the sole user of the disk.
