Subject: [PATCH net-next 0/3] bpf: share helpers between tracing and networking

Introduce new helpers to access 'struct task_struct'->pid, tgid, uid, gid, comm
fields in tracing and networking.

Share bpf_trace_printk() and bpf_get_smp_processor_id() helpers between
tracing and networking.

Alexei Starovoitov (3):
  bpf: introduce current->pid, tgid, uid, gid, comm accessors
  bpf: allow networking programs to use bpf_trace_printk() for
    debugging
  bpf: let kprobe programs use bpf_get_smp_processor_id() helper
