Subject: [PATCHv3 perf/core 0/7] Reuse libbpf from samples/bpf

(Was "libbpf: Synchronize implementations")

Update tools/lib/bpf to provide the remaining bpf wrapper pieces needed by the
samples/bpf/ code, then get rid of all of the duplicate BPF libraries in
samples/bpf/libbpf.[ch].

---
v3: Add ack for first patch.
    Split out second patch from v2 into separate changes for remaining diff.
    Add patches to switch samples/bpf over to using tools/lib/.
v2: https://www.mail-archive.com/netdev@vger.kernel.org/msg135088.html
    Don't shift non-bpf code into libbpf.
    Drop the patch to synchronize ELF definitions with tc.
v1: https://www.mail-archive.com/netdev@vger.kernel.org/msg135088.html
    First post.

Joe Stringer (7):
  tools lib bpf: Sync {tools,}/include/uapi/linux/bpf.h
  tools lib bpf: use __u32 from linux/types.h
  tools lib bpf: Add flags to bpf_create_map()
  samples/bpf: Make samples more libbpf-centric
  samples/bpf: Switch over to libbpf
  samples/bpf: Remove perf_event_open() declaration
  samples/bpf: Move open_raw_sock to separate header
