Applied.
In patch 5 I had to fix:
/data/users/ast/net-next/tools/testing/selftests/bpf/prog_tests/xdp_devmap_attach.c:
In function ‘test_neg_xdp_devmap_helpers’:
/data/users/ast/net-next/tools/testing/selftests/bpf/test_progs.h:106:3:
warning: ‘duration’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
106 | fprintf(stdout, "%s:PASS:%s %d nsec\n", \
| ^~~~~~~
/data/users/ast/net-next/tools/testing/selftests/bpf/prog_tests/xdp_devmap_attach.c:79:8:
note: ‘duration’ was declared here
79 | __u32 duration;
and that selftest is imo too primitive.
It's only loading progs and not executing them.
Could you please add prog_test_run to it?
