[PATCH 0/3] perf/core: Optimize LBR callstack handling

[Namhyung Kim]

Hello,

I found other problematic cases wrt LBR callstacks.  Basically O(N^2)
loop for every threads is too costly on large machines.  We can use
faster memory allocation and free methods to reduce the overhead.

Actually this approach is suggested by AI (Gemini).

Thanks,
Namhyung
