If the root dentry implements d_dname instead of ignoring it in __dentry_path call d_dname and return the result. The motivating example are files under /proc/<pid>/ns/ are bind mounted into other locations. This change allow the name of the dentry that is bind mounted to show up in /proc/<pid>/mountinfo. However in general this is correct behavior any time dentry_path is called on a dentry that implements d_dname. Signed-off-by: "Eric W.
