Interesting: I didn't get an email that this got queued to 6.1.165, 
note: this is not in 6.1.165-rc1, but in 6.1.165-rc2.

I only got: FAILED: Patch "x86/kexec: add a sanity check on previous 
kernel's ima kexec buffer" failed to apply to 6.1-stable tree

In any case: we need a prerequisite for this, so I will work on 
backports in a few days, I think for now, we should drop this commit 
from 6.1.y.

Also I see something unusual -->

6.1.165-rc1 --> 232 patches.

6.1.165-rc2 --> 533 patches.

Can you please check ?


Thanks,
Harshit
