From 6f94a72d45295741b8be64da40a86780c7681a3b Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 4 Apr 2024 10:57:15 -0700 Subject: perf annotate: Move nr_events struct to 'struct annotated_source' It's only used in 'perf annotate' output which means functions with actual samples. No need to consume memory for every symbol ('struct annotation').
