I checked and I guess you are referring to the initial state of the
buffer_size_kb, which returns:
0 (expanded: 1408)
instead of:
7 (expanded: 1408)

I found this got in with the earlier patch which added per-cpu
buffer_size_kb. I will send a small fix-up patch for it.

After expanding the ring buffer to various sizes, I couldn't find any
other breakage. Is there any other behavior that you saw as odd?
