Yes it is possible. A MR can be created with an iov_base of say 0xffffffff00000000. Then any sge.addr entries would be the iob_base + any offset.
Anyway please send me this change as a separate patch with a changelog explaining that you're avoiding the div etc.... I don't want to roll it in with the other unrelated fix (which changes code that was never upstream anyway).
will do. So you are handling the offset patch that will make it u64 and remove the mod usage, correct?
I will post a new patch with just this send change. Steve. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
