CentOS - Jan 2022 - Kernel live patching on CentOS Stream 9

Dear all,
is kernel live patching working for CentOS Stream 9?

I know that I can enable it via cockpit or the command line, but are 
kernel patch files really available or do they require an active RHEL 
subscription?

Thanks.

There are 2 things to note here about kernel live patching:
- We do not provide patch files in CentOS Stream (or previously in
CentOS Linux, for that matter). We've always recommended RHEL as a
better fit for folks that have hard requirements on this sort of
workflow.
- RHEL 9 is not yet released, my understanding is that patch files for
RHEL proper will begin showing up after GA

My understanding of live kernel patching is that the feature allows 
systems to update specific individual kernel functions, and is primarily 
useful for addressing security vulnerabilities (and not, for example, 
for updating from one kernel version to another).? I don't know for a 
fact, but my expectation is that CentOS Stream systems aren't going to 
get "live" patches because there's no ongoing support for
individual
kernels.
