fs/ufs: recognize Solaris-specific file system state
Recent releases of Solaris set the fs_clean state of an unmounted UFS file system as FSLOG ("logging fs"). 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.
