From c2f92e8b2d24615acda3fc571180d8b44a710df5 Mon Sep 17 00:00:00 2001 From: Ross Zwisler Date: Mon, 13 Mar 2023 15:17:45 -0600 Subject: [PATCH] tools/kvm_stat: use canonical ftrace path The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A comment in kvm_stat still refers to this older debugfs path, so let's update it to avoid confusion.
