Got it. > https://github.com/microsoft/WSL2-Linux-Kernel?tab=readme-ov-file#feature-requests tells me submitting the change upstream. That's true in general,but in this case because the driver itself is not upstreamed yet so it cannot be applied. Don't let this discourage you. If you author changes to code that is already upstreamed, do submit them to the respective mailing lists. Thanks, Wei. > > Regards, > Lang > > >Thanks, > >Wei.
