Huh, actually it's not __counted_by() since this shows up with arm64/gcc-10 (and some other arches) which doesn't have that. I'll submit the __counted_by() patch anyway since it's clearly a good annotation but it doesn't actually shut the warning up in this case. Adding the hardening people, and I'll have a further look. You can reproduce with tuxmake -r docker -k defconfig -a arm64 -t gcc-10 using https://www.tuxmake.org/
