We found a compile error when building tools/testing/selftests/bpf/ on 5.10.y.
tools/testing/selftests/bpf/prog_tests/sk_lookup.c:1092:15: error: 'struct bpf_sk_lookup' has no member named 'cookie'
1092 | if (CHECK(ctx.cookie == 0, "ctx.cookie", "no socket selected\n"))

To fix this bug, this patchset backports three patches from upstream:
https://lore.kernel.org/bpf/20210303101816.36774-1-lmb@xxxxxxxxxxxxxx/
Patch 1 and 2 are necessary for bpf selftests build pass on 5.10.y.
Patch 3 does not impact building stage, but can avoid a test case
failure (by skipping it).
Lorenz Bauer (3):
bpf: Consolidate shared test timing code
bpf: Add PROG_TEST_RUN support for sk_lookup programs
selftests: bpf: Don't run sk_lookup in verifier tests
