[PATCH v3 bpf-next 0/6] BPF sk local storage

[Martin KaFai Lau <kafai@fb.com>]

v3:
- Replace spinlock_types.h with spinlock.h in patch 1
  (kbuild test robot <lkp@intel.com>)

v2:
- Add the "test_maps.h" file in patch 5

This series introduces the BPF sk local storage.  The
details is in the patch 1 commit message.

Martin KaFai Lau (6):
  bpf: Introduce bpf sk local storage
  bpf: Sync bpf.h to tools
  bpf: Support BPF_MAP_TYPE_SK_STORAGE in bpf map probing
  bpf: Add verifier tests for the bpf_sk_storage
  bpf: Add BPF_MAP_TYPE_SK_STORAGE test to test_maps
  bpf: Add ene-to-end test for bpf_sk_storage_* helpers
