The size increase makes this a complete non-starter in the embedded configs I'm familiar with. Size is still the number one problem using Linux in consumer electronics products. I have nothing against this patch, if it achieve some speedups for other environments. But I wouldn't expect to see this option used much in embedded devices. -- Tim ============================= Tim Bird Architecture Group Chair, CE Linux Forum Senior Staff Engineer, Sony Corporation of America =============================
