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.
