Jiri Olsa c458a6206d perf tools: Fix tracing_path_mount proper path ... If there's no tracefs (RHEL7) support the tracing_path_mount returns debugfs path which results in following fail: # perf probe sys_write kprobe_events file does not exist - please rebuild kernel with CONFIG_KPROBE_EVENTS. Error: Failed to add events. In tracing_path_debugfs_mount function we need to return the 'tracing' path instead of just the mount to make it work: # perf probe sys_write Added new event: probe:sys_write (on sys_write) You can now use it in all perf tools, such as: perf record -e probe:sys_write -aR sleep 1 Adding the 'return tracing_path;' also to tracing_path_tracefs_mount function just for consistency with tracing_path_debugfs_mount. Upstream keeps working, because it has the tracefs support.
