Subject: [PATCH v2 bpf-next 0/4] bpf: Enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP

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

Martin KaFai Lau (4):
  bpf: Folding omem_charge() into sk_storage_charge()
  bpf: Rename some functions in bpf_sk_storage
  bpf: Allow using bpf_sk_storage in FENTRY/FEXIT/RAW_TP
  bpf: selftest: Use bpf_sk_storage in FENTRY/FEXIT/RAW_TP
