Ah wait. I thought this was the shared-memory patch. More haste, less speed and all that. I guess it should really go into the -rcs, yes. Since Hans' patch actually breaks a lot of devices. I'm pretty surprised a patch capable of this much damage was actually accepted to be honest. A better approach would have been to issue a warning, but keep the semantics the same for at least a couple of releases. However, I guess the damage has been done now, so let's do what we can do fix it. -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
