From b19a0f610088a1416d118b4f89b1e2fda9eeb7ca Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Mon, 29 Sep 2025 10:06:00 -0700 Subject: [PATCH] perf build: Remove libtracefs configuration libtracefs isn't used by perf but not having it installed causes build warnings. Given the library isn't used, there is no need for the configuration or warnings so remove.
