From: Vivek Goyal <[email protected]> Right now OVL_PATH_MERGE is used only for merged directories. But conceptually, a metacopy dentry (backed by a lower data dentry) is a merged entity as well.
So mark metacopy dentries as OVL_PATH_MERGE and ovl_rename() makes use of this property later to set redirect on a metacopy file.
