Yes, this issue wave been there already for a long time, but, as we were checking each part of ABI files in separate, there was no way to detect in the past. With the recent changes, all ABI symbols are parsed altogether. So, symbol duplication on different parts of ABI (in this specific case stable and testing) are now detected. I wrote already a patch fixing it as part of my original RFC: https://lore.kernel.org/linux-doc/673e9543783349b0fcf625018e38e4e93fe98f52.1738020236.git.mchehab+huawei@kernel.org/ It ended that I placed it on a bucket of patches to be sent later on. I'm re-sending it right now as a normal patch. Thanks, Mauro
