No need for compat_ioctl handlers as there are no ioctls involved in aio, we just need better compat versions of io_submit, which by itself is a bit of an ioctl-like multiplexer. Adding the vector compat might be a bit messy, but shouldn't be too hard given that we already deal with this for native (p)readv/(p)writev. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
