Subject: [PATCH v2 bpf-next 0/3] bpf: increase jmp sequence limit

Patch 1 - jmp sequence limit
Patch 2 - improve existing tests
Patch 3 - add pyperf-based realistic bpf program that takes advantage
of higher limit and use it as a stress test

v1->v2: fixed nit in patch 3. added Andrii's acks

Alexei Starovoitov (3):
  bpf: bump jmp sequence limit
  selftests/bpf: adjust verifier scale test
  selftests/bpf: add pyperf scale test
