Subject: [PATCH bpf-next 0/3] Various BPF exception improvements

Two small improves to BPF exceptions in this patchset:

1. Allow throwing exceptions in XDP progs
2. Add some macros to help release references before throwing exceptions

Note the macros are intended to be temporary, at least until BPF
exception infra is able to automatically release acquired resources.

Daniel Xu (3):
  bpf: xdp: Register generic_kfunc_set with XDP programs
  bpf: selftests: Add bpf_assert_if() and bpf_assert_with_if() macros
  bpf: selftests: Test bpf_assert_if() and bpf_assert_with_if()
