v1->v2: switched to init_user_ns from current_user_ns as suggested by Andy
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
