    ovl: do not cleanup directory and whiteout index entries · 61b67471
    Amir Goldstein authored
    Directory index entries are going to be used for looking up
    redirected upper dirs by lower dir fh when decoding an overlay
    file handle of a merge dir.
    Whiteout index entries are going to be used as an indication that
    an exported overlay file handle should be treated as stale (i.e.
    after unlink of the overlay inode).
    We don't know the verification rules for directory and whiteout
    index entries, because they have not been implemented yet, so fail
    to mount overlay rw if those entries are found to avoid corrupting
    an index that was created by a newer kernel.
