Subject: [PATCH bpf-next 0/3] 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 patch is a cleanup.  The last patch is
tests.  The second patch has the required kernel changes to
enable bpf_sk_storage for FENTRY/FEXIT/RAW_TP.

Please see individual patch for details.

Martin KaFai Lau (3):
  bpf: Folding omem_charge() into sk_storage_charge()
  bpf: Allow using bpf_sk_storage in FENTRY/FEXIT/RAW_TP
  bpf: selftest: Use bpf_sk_storage in FENTRY/FEXIT/RAW_TP
