Yes, this is the target of the patch. Can we put the change in the
Hyper-V patchset?


If you're asking about this version:

https://lore.kernel.org/r/20211020062321.3581158-1-ltykernel@xxxxxxxxx

then, no. I'd prefer if you did this:

https://lore.kernel.org/r/YXAcGtxe08XiHBFH@xxxxxxx

for reasons which I already explained.

Thanks for your suggestion. I just sent out v8 version according to yourguide. Please have a look.



Thanks.
