I am seeing several warnings/errors from both GCC and Clang with ARCH=arm64 allmodconfig after this series appeared in next-20240906. As far as I can tell, they appear to agree. I wondered how this was not caught during the series development but perhaps it was written against a development tree that did not have Arnd's extrawarn series from 6.10 in it yet? I was going to work on a series but I was not sure about the best way to address the overflow errors, hence just the report.
