If the release function is a noop, lots of memory in the kernel is leaking. UIO shouldn't have to do anything special here, is the devm api somehow broken? If so, let's fix that, not paper over all other driver bugs by moving the UIO code away from it :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
