when handle_open() encounters a file of type NF4LNK and the FILE_OPEN_REPARSE_POINT flag is not present, it calls READLINK for the symlink's target path. it then calls abs_path_link() to update the filename (args->path), whether the symlink target is an absolute or relative path. abs_path_link() also takes into account the special characters . and .., though it doesn't allow traversing .. entries below the root of the server's namespace

on last_error == ERROR_REPARSE, the daemon converts args->path back to wchar and passes it down to the driver

caused memory leaks of nfs41_open_state. we have the FileDispositionInformation upcall for exactly this, so there's no need to complicate the close code path
