Subject: [PATCH v4 3/3] tools/kvm_stat: use canonical ftrace path

From: Ross Zwisler <>

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:


A comment in kvm_stat still refers to this older debugfs path, so let's
update it to avoid confusion.
