If anyone has any objections, please let me know. ------------------ From: Jiri Olsa commit 275ef3878f698941353780440fec6926107a320b upstream. If the event name is specified with all 3 components, the last one overwrites the previous one during the name composing within the parse_events_add_cache function. Fixing this by properly adjusting the string index.
