This should probably be done with a sysfs attribute so that it can be turned on and off as desired. Off by default, of course. Some other subsystems already support error injection, you could check how they are doing it, do that we do not diverge needlessly. Do you think there is any value in failing with different error codes, or just -EIO is enough? Do you think it should fail all the time when error injection is enabled, or is there a value in having only a certain % of commands fail? -- Jean Delvare SUSE L3 Support -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
