The last remaining place (resolution of nested symlink) converted to the loop of the same kind we have in path_lookupat() and path_openat(). Note that we still *do* have a recursion in pathname resolution; can't avoid it, really. However, it's strictly for nested symlinks now - i.e. ones in the middle of a pathname. link_path_walk() has lost the tail now - it always walks everything except the last component. do_follow_link() renamed to nested_symlink() and moved down.
