Also I don't really understand why we're even discussing this. The patch only makes an widely used API behave as it was before. Who knows who else was broken with this change. There's no sane way to audit all users. There is no real advantage of the new behavior. The only good way is to revert to old behavior, like in Tim's original patch. And doing it quickly for mainline and stable. FWIW we have a large number of systems here that are broken without this change. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- 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
