From: Ihor Solodrai <ihor.solodrai@pm.me> mainline inclusion from mainline-v6.12-rc6 commit 9b3c11a867a82ebee4e096008014417918b82801 category: feature bugzilla: https://atomgit.com/openeuler/kernel/issues/8335 Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... -------------------------------- The runner.o may start building before libbpf headers are installed, and as a result build fails. This happened a couple of times on libbpf/ci test jobs: * https://github.com/libbpf/ci/actions/runs/11447667257/job/31849533100 * https://github.com/theihor/libbpf-ci/actions/runs/11445162764/job/3184164955... Headers are installed in a recipe for $(BPFOBJ) target, and adding an order-only dependency should ensure this doesn't happen.
