[PATCH v2 bpf-next 0/5] bpf: volatile compare

[Alexei Starovoitov <alexei.starovoitov@xxxxxxxxx>]

From: Alexei Starovoitov <ast@xxxxxxxxxx>

v1->v2:
Fixed issues pointed out by Daniel, added more tests, attempted to convert profiler.c,
but barrier_var() wins vs bpf_cmp(). To be investigated.
Patches 1-4 are good to go, but 5 needs more work.

Alexei Starovoitov (5):
  selftests/bpf: Attempt to build BPF programs with -Wsign-compare
  bpf: Introduce "volatile compare" macro
  selftests/bpf: Convert exceptions_assert.c to bpf_cmp
  selftests/bpf: Remove bpf_assert_eq-like macros.
  selftests/bpf: Attempt to convert profiler.c to bpf_cmp.
