====================
This patch allows to specify program flags and multiple verifier log
messages for the test_loader kind of tests. For example:
tools/testing/selftets/bpf/progs/foobar.c:
SEC("tc")
__success __log_level(7)
__msg("first message")
__msg("next message")
__flag(BPF_F_ANY_ALIGNMENT)
int buz(struct __sk_buff *skb)
{ ... }
It was developed by Andrii Nakryiko ([1]), I reused it in a
"test_verifier tests migration to inline assembly" patch series ([2]),
but the series is currently stuck on my side.
Andrii asked to spin this particular patch separately ([3]).
