selftests/bpf: retry tests that expect build-id
While running test_progs in a loop I found out that I'm sometimes hitting "Didn't find expected build ID from the map" error. Looking at stack_map_get_build_id_offset() it seems that it is racy (by design) and can sometimes return BPF_STACK_BUILD_ID_IP (i.e. can't trylock current->mm->mmap_sem). Let's retry this test a single time. Fixes: 13790d1c ("bpf: add selftest for stackmap with build_id in NMI context") Acked-by:Song Liu <songliubraving@fb.com> Signed-off-by:
