Yes, just checked, commit 9a1ac2288cf1 was merged in 5.11-rc1, not in
5.10.0. Seems Redhat CKI doesn't treat the kernel release correctly, it
calls all kernel 5.11-rcx as 5.10.0. Sorry for the confusion, I will
send mail to them to change this.

I got the failure report from redhat's CKI test, the kernel repo is as
below, but the subject of failure report and 'uname -r' told it's
5.10.0.
