What Michal said, replace 874bbfe6 with 176bed1d. Without 22b886dd, 874bbfe6 is a landmine, uses add_timer_on() as if it were mod_timer(), which it is not, or rather was not until 22b886dd came along, and still does not look like the mod_timer() alias that add_timer() is. -Mike -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
