Oh, then I was wrong about it. I add linux-next repo in my linux kernel
folder, so I can't get it with the above command on master branch of
mainline kernel:

[bhe@~ linux]$ git describe --contains 9a56493f6942
next-20200820~107^2~8

I just use 'git log --oneline' and found out commit 9a56493f6942 is
added before 5.9-rc1. Seems this is not right way to get the kernel
release. So please ignore the back porting request of stable tree.
Sorry about the confusion.

Thanks
Baoquan
