Hello. > I haven't identified which NULL in udev_monitor_receive_device() is returned. I identified that "recvmsg() in udev_monitor_receive_device() returning ENOBUFS error" is the cause of "udev_monitor_receive_device() returning NULL". Therefore, I moved the discussion to LP #1215911. https://launchpad.net/bugs/1215911 Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
