Subject: [bpf-next PATCH 0/3] bpf: Add sk_msg helpers 

This series adds helpers for sk_msg program type.

Add a set of helpers that makes sk_msg more useful. Notable add the
*current_task* getters and the probe_* routines guarded by a capabilities
check for CAP_SYS_ADMIN.

 BPF_FUNC_perf_event_output
 BPF_FUNC_get_current_uid_gid
 BPF_FUNC_get_current_pid_tgid
 BPF_FUNC_get_current_cgroup_id
 BPF_FUNC_get_current_ancestor_cgroup_id
 BPF_FUNC_get_cgroup_classid

 BPF_FUNC_get_current_task
 BPF_FUNC_current_task_under_cgroup
 BPF_FUNC_probe_read_user
 BPF_FUNC_probe_read_kernel
 BPF_FUNC_probe_read
 BPF_FUNC_probe_read_user_str
 BPF_FUNC_probe_read_kernel_str
 BPF_FUNC_probe_read_str

 BPF_FUNC_sk_storage_get
 BPF_FUNC_sk_storage_delete

I have an RFC test for sk_storage_* patch that is pending merge of
other sockmap_test patches.
