The 5th parameter of filldir_t function type used by vfs_readdir was changed from ino_t to u64 in October. Unfortunately the patch missed some files in fs/nfsd where functions pointers of type encode_dent_fn are passed around and finally cast to filldir_t.
The effect is only visible when an NFS server is run on a 32 bit big-endian machine (it would have been visible on all 32 bit architectures if the 6th parameter had been used). The results are interesting: all files have an inode of 0 (unique you say?) from getdents(2) and even ls(1) does not find any files.
