    Make reiserfs3 return f_fsid info for statfs(2).  By Andreas' suggestion,
    this patch populates a persistent f_fsid between boots/mounts with help of
    on-disk uuid record.
    
    Randy Dunlap reported a compiling error from v2 patch like:
        fs/built-in.o: In function `reiserfs_statfs':
        super.c:(.text+0x7332b): undefined reference to `crc32_le'
        super.c:(.text+0x7333f): undefined reference to `crc32_le'
    Also he provided helpful solution to fix this error. The modification of v3
    patch is based on Randy's suggestion, add 'select CRC32' in fs/reiserfs/Kconfig.
