From 9f30fffc78ca35c862f74f34cc597c7fdddc8793 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 26 Aug 2015 15:46:45 +0200 Subject: [PATCH] perf tools: Do not change lib/api/fs/debugfs directly The tracing_events_path is the variable we want to change via --debugfs-dir option, not the debugfs_mountpoint.
