Merge branch 'bpf: Enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP'
Martin KaFai says:
====================
This set is to allow the FENTRY/FEXIT/RAW_TP tracing program to use
bpf_sk_storage. The first two patches are a cleanup. The last patch is
tests. Patch 3 has the required kernel changes to
enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP.
Please see individual patch for details.
v2:
- Rename some of the function prefix from sk_storage to bpf_sk_storage
- Use prefix check instead of substr check
====================
