This is indeed rather ugly - and the other patch that removes a debug
check seems counterproductive as well.

Do we know how many genuine bugs -Wstringop-overread-warning has
caught or is about to catch?

I.e. the real workaround might be to turn off the -Wstringop-overread-warning,
until GCC-11 gets fixed?

See the [PATCH 0/11] message. The last two patches in the series are for
code that I suspect may be broken, the others are basically all false positives.

As gcc-11 is not released yet, I don't think we have to apply any of the
patches or disable the warning at the moment, but I posted all the patches
to get a better understanding on which of them should be addressed in
the kernel vs gcc.
