However, the Linux kernel currently does not recognize the value which represents this state. Thus, attempting to mount such a file system rw produces the message kernel: ufs_read_super: can't grok fs_clean 0xfffffffd and the file system is mounted read-only. This patch makes the kernel recognize that value.
