We(Huawei) are willing to commit resources to help out in testing the
stable -rc releases, and to help to backport patches for stable kernels.

5.10 stable kernel will be used for openEuler [1] kernel and also inside
Huawei. From customer's feedback, it's very important to see the stable
kernel we used to be maintained for 6 years in the community, and we
will use 5.10 kernel for at least 6 years, so we are willing to help
you and help ourselves :)

In specific, we will start from the testing work, using HULK robot
(reports lots of bugs to mainline kernel) testing framework to test
compile, reboot, functional testing, and will extend to basic
performance regression testing in the future.

And we will start from ARM64 and X86 architecture first, and then extend
to other platforms.

For patch backporting, will send the bugfix patches (from mainline)
we spotted, but I think this work may not doing in regular but will
be triggered as needed.

Does this sound good to you?

Thanks
Hanjun
