Subject[PATCH v2 bpf-next 0/2] Allow attaching to bare tracepoints
Date
Changes in v2:
* Fix compilation error.
* Make the new test use write() instead of read()

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're no
events in tracefs created with them.

selftests: bpf: Add a new test for bare tracepoints
