Fix that by checking whether the signal > is handled. Why? Even if the application handles the signal, the point of this debugging is to have the kernel report the reason for the fault. Just because the application has installed a SIGSEGV handler to print some nice "oops" message, and to cleanly shut down (eg, like Xorg) doesn't mean we should hide this debugging. In fact, as such handlers generally get in the way of getting a decent dump from the application, having the kernel report this information is even more valuable in this situation. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
