From: Chuck Lever <[email protected]> NFS and other remote filesystem protocols need to determine whether a local filesystem performs case-insensitive lookups so they can provide correct semantics to clients. Without this information, f2fs exports cannot properly advertise their filename case behavior.
Report f2fs case sensitivity behavior via the file_kattr boolean fields. Like ext4, f2fs supports per-directory case folding via the casefold flag (IS_CASEFOLDED). Files are always case-preserving.
