2020-01-20samples/bpf: Use consistent include paths for libbpfToke Høiland-Jørgensen1-1/+1
Fix all files in samples/bpf to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.

2019-06-18samples: bpf: refactor header include pathDaniel T. Lee1-1/+1
Currently, header inclusion in each file is inconsistent. For example, "libbpf.h" header is included as multiple ways. #include "bpf/libbpf.h" #include "libbpf.h" Due to commit b552d33c80a9 ("samples/bpf: fix include path in Makefile"), $(srctree)/tools/lib/bpf/ path had been included during build, path "bpf/" in header isn't necessary anymore. This commit removes path "bpf/" in header inclusion. Signed-off-by: Daniel T. Lee <danieltimlee@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
