Having the bpf/ subdir of $INCLUDEDIR in the include path has never been a requirement for building against libbpf before, and indeed the libbpf pkg-config file doesn't include it. So let's make all libbpf includes across the kernel tree use the bpf/ prefix in their includes. Since bpftool skeleton generation emits code with a libbpf include, this also ensures that those can be used in existing external projects using the regular pkg-config include path. This turns out to be a somewhat invasive change in the number of files touched; however, the actual changes to files are fairly trivial (most of them are simply made with 'sed'). The series is split to make the change for one tool subdir at a time, while trying not to break the build along the way. It is structured like this: - Patch 1-3: Trivial fixes to Makefiles for issues I discovered while changing the include paths. - Patch 4-8: Change the include directives to use the bpf/ prefix, and updates Makefiles to make sure tools/lib/ is part of the include path, but without removing tools/lib/bpf - Patch 9-11: Remove tools/lib/bpf from include paths to make sure we don't inadvertently re-introduce includes without the bpf/ prefix. Changelog: v5: - Combine the libbpf build rules in selftests Makefile (using Andrii's suggestion for a make rule). - Re-use self-tests libbpf build for runqslower (new patch 10) - Formatting fixes v4: - Move runqslower error on missing BTF into make rule - Make sure we don't always force a rebuild selftests - Rebase on latest bpf-next (dropping patch 11) v3: - Don't add the kernel build dir to the runqslower Makefile, pass it in from selftests instead. - Use libbpf's 'make install_headers' in selftests instead of trying to generate bpf_helper_defs.h in-place (to also work on read-only filesystems). - Use a scratch builddir for both libbpf and bpftool when building in selftests. - Revert bpf_helpers.h to quoted include instead of angled include with a bpf/ prefix. - Fix a few style nits from Andrii v2: - Do a full cleanup of libbpf includes instead of just changing the bpf_helper_defs.h include.
