[PATCH bpf-next 0/2] Allow attaching to bare tracepoints

From: Qais Yousef <hidden>
Date: 2021-01-11 18:21:33
Also in: bpf, lkml

Add some missing glue logic to teach bpf about bare tracepoints - tracepoints
without any trace event associated with them.

Bare tracepoints are declare with DECLARE_TRACE(). Full tracepoints are declare
with TRACE_EVENT().

BPF can attach to these tracepoints as RAW_TRACEPOINT() only as there's no
events in tracefs created with them.

Qais Yousef (2):
  trace: bpf: Allow bpf to attach to bare tracepoints
  selftests: bpf: Add a new test for bare tracepoints
