Hi, I'm trying to understand the flight recorder mode (including the hybrid one) of LTTng. I originally expected that this mode means: 1. Fixed set of buffers, older data will be overwritten on wrap-around 2. Limited size of trace files While 1. seems to be true, 2. is neither what I observe in the output directory (flight-cpu_* get larger and larger) nor what I can find in lttd's code. Intentionally?
