The situation highlighted by Coverity does not appear to be possible given the current use of the API. However, it should still be checked to catch future errors (or current bugs). 1412200 Dereference after null check Either the check against null is unnecessary, or there may be a null pointer dereference. In lttng_trace_chunk_rename_path_no_lock: Pointer is checked against null but then dereferenced anyway (CWE-476) Reported-by: Coverity Scan Signed-off-by: Jérémie Galarneau Change-Id: I991231cc636eaed98cb84eec08a5072748ff9ef4 ---
