Steven Rostedt 318e0a73c9 tracing: remove on the fly allocator from function profiler ... Impact: safer code The on the fly allocator for the function profiler was to save memory. But at the expense of stability. Although it survived several tests, allocating from the function tracer is just too risky, just to save space. This patch removes the allocator and simply allocates enough entries at start up. Each function gets a profiling structure of 40 bytes. With an average of 20K functions, and this is for each CPU, we have 800K per online CPU. This is not too bad, at least for non-embedded.
