Merge branch 'Allow attaching to bare tracepoints'
Qais Yousef says:
====================
Changes in v3:
* Fix not returning error value correctly in
trigger_module_test_write() (Yonghong)
* Add Yonghong acked-by to patch 1.
Changes in v2:
* Fix compilation error. (Andrii)
* Make the new test use write() instead of read() (Andrii)
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.
