In kernel 6.19-rc7, this kernel option still exists in the file

tools/testing/selftests/liveupdate/config. Thus I send out this commit 
to remove it.

Yes, but the patch to add the config is in mm-nonmm-unstable. I am not
sure if this worth the churn of removing this and re-adding it when that
patch lands later. Do you see a real problem with this?

Thanks for the feedback.

I understand that the patch adding this functionality is currently in 
mm-nonmm-unstable. My concern was primarily adhering to the 
documentation, which suggests keeping the kernel configs pruned of 
unused options to avoid confusion for those running selftests.

However, I see your point regarding the churn. If you prefer, we can 
wait until the mm-nonmm-unstable branch is merged into the mainline. 
Once that happens, if this option remains truly redundant or if the 
implementation changes, I can resubmit the cleanup then.

Does that sound like a reasonable compromise to you?

Best regards,

Yes, sounds good. And even though I don't recommend taking this patch
right now, the effort to keep things clean is much appreciated!
