    ovl: lookup indexed ancestor of lower dir · 06170154
    Amir Goldstein authored
    ovl_lookup_real() in lower layer walks back lower parents to find the
    topmost indexed parent. If an indexed ancestor is found before reaching
    lower layer root, ovl_lookup_real() is called recursively with upper
    layer to walk back from indexed upper to the topmost connected/hashed
    upper parent (or up to root).
    
    ovl_lookup_real() in upper layer then walks forward to connect the topmost
    upper overlay dir dentry and ovl_lookup_real() in lower layer continues to
    walk forward to connect the decoded lower overlay dir dentry.
