Subject: [PATCH bpf-next v2 0/7] bpf: teach the verifier about JSET and add tests

Hi!

This is a v2 of the patch set to teach the verifier about BPF_JSET
instruction.  There is also a number of tests include for both
basic functioning of the instruction and the verifier logic.
The NFP JIT handling of JSET is tweaked.  Last patch adds missing
file to gitignore.

Reposting part of previous series without the dead code elimination.

Jakub Kicinski (7):
  selftests: bpf: add trivial JSET tests
  bpf: verifier: teach the verifier to reason about the BPF_JSET
    instruction
  selftests: bpf: verifier: add tests for JSET interpretation
  bpf: verifier: reorder stack size check with dead code sanitization
  nfp: bpf: remove the trivial JSET optimization
  nfp: bpf: optimize codegen for JSET with a constant
  selftests: bpf: add missing executables to .gitignore
