It'd be good if someone could update the documentation in the mutex code so the usage were clear here - I don't want to see the locking become any more complicated, especially not for relatively infrequently used things like supplies. Though we may be able to deal with this by simplifying the implementation of supplies anyway. -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
