For my next patch, would it help if I clearly explain the root cause, my reasoning, and the solution in the commit message or cover letter? I'd like to make review smoother.

I don't care, the policy is there, and all active developers are 
following it:

https://docs.kernel.org/process/coding-assistants.html


I see no point why you want to be special and do not disclose whether 
you have used LLM, unless you have something to hide and then I have all 
reasons to question your motivation.

Even well known developers are using LLM actively, e.g:

https://lore.kernel.org/linux-btrfs/20260811-btrfs-enomem-v3-0-46a993fc3fe5@xxxxxxxxxx/

https://lore.kernel.org/linux-btrfs/69d0043e0f6a3d17048dfde857127ab0bf331154.1785190866.git.boris@xxxxxx/

And of course myself:

https://lore.kernel.org/linux-btrfs/61fd5ab4b532ba3a7915dc629339db230cccd52f.1786007917.git.wqu@xxxxxxxx/

It's very simple, if you used LLM to analyze/fix the bug, then just 
disclose it.
