Eric, can you please suggest what we should do here? Yes, the ENOMEM is bogus. But irda_sysctl_register() saw a NULL return from register_sysctl_table() and simply has no clue why it failed, and is forced to assume ENOMEM. That's a design shortcoming in register_sysctl_table(), whcih should have returned an ERR_PTR. Doesn't matter much. - 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/
