No, just my patch or your patch, base on upstream codes(kernel branch is
linux-next and xen branch is staging).

That's fine, feel free to send me if you need more test information.
Actually I am still continuing to debug your patch and also curious about why
your patch does not work.
The only difference between our methods is the timing of updating the size.
Yours is later than mine because you updated the size when the driver
re-enabled memory decoding, while I updated the size in time when driver resize
it.
I suspect that the driver or hypervisor may have done something in between and
read outdated information.
I am debugging the driver codes.
