(Or have ext4_dirhash call the normalization function, but that would require passing the sbi->encoding to ext4_dirhash) That way we can do efficient lookups even if the lookup uses a different normalized form than what was originally used when the file was created. (We can also use this to do efficient hash lookups once we add case folding support.) - Ted
