Adrian Hunter 03db8b583d perf tools: Fix maps__find_symbol_by_name() ... Commit 1c5aae7710 ("perf machine: Create maps for x86 PTI entry trampolines") revealed a problem with maps__find_symbol_by_name() that resulted in probes not being found e.g. $ sudo perf probe xsk_mmap xsk_mmap is out of .text, skip it. Probe point 'xsk_mmap' not found. Error: Failed to add events. maps__find_symbol_by_name() can optionally return the map of the found symbol. It can get the map wrong because, in fact, the symbol is found on the map's dso, not allowing for the possibility that the dso has more than one map. Fix by always checking the map contains the symbol.
