Could you please rewrite the above into a simple loop. Something along the lines of: for(;;) { ... if (clnt == clnt->cl_parent) break; clnt = clnt->cl_parent; } -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com ��.n��������+%������w��{.n�����{��w���jg��������ݢj����G�������j:+v���w�m������w�������h�����٥
