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.
