Date: Fri, 18 Apr 2014 12:31:57 +0200 From: Jiri Olsa <jolsa@...hat.com> To: Ingo Molnar <mingo@...nel.org> Cc: linux-kernel@...r.kernel.org, Don Zickus <dzickus@...hat.com>, Jiri Olsa <jolsa@...hat.com> Subject: [PATCH 3/5] perf tools: Use cpu/possible instead of cpu/kernel_max From: Don Zickus <dzickus@...hat.com> The system's max configuration is represented by cpu/possible and cpu/kernel_max can be huge (4096 vs. 128), so save space by keeping smaller structures.
