On the signal side these both should be implemented in the same way -- if there was really a missing signal_pending() check somewhere then Ctrl-Z (and kill) should be delayed too. Now doing faster signal processing is always a good thing in general, but I'm a little doubtful your patch will help with that particular problem. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
