The next-20241011 release gets me build errors like the following: vmlinux.o: warning: objtool: fetch_item() falls through to next function Bisection leads me here: 61595012f280 ("HID: simplify code in fetch_item()") This diff looks inoffensive to me, but I get this error on this commit and not on its predecessor. This build failure happens on quite a few different kernel configurations. I bisected using this particular reproducer: tools/testing/selftests/rcutorture/bin/kvm.sh --allcpus --buildonly --configs SRCU-T Thoughts? Thanx, Paul
