Merge branch 'bpf-improve-test-verifier-coverage'
Alexei Starovoitov says:
====================
BPF verifier has 700+ tests used to check correctness of the verifier.
Beyond checking the verifier log tell kernel to run accepted programs
as well via bpf_prog_test_run() command. That improves quality of the
tests and increases bpf test coverage.
