Subject[for-next][PATCH 10/25] tools/kvm_stat: use canonical ftrace path
From: Ross Zwisler <zwisler@google.com>

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.

All available events have directories under
- /sys/kernel/debug/tracing/events/ which export information
+ /sys/kernel/tracing/events/ which export information
about the specific event. Therefore, listing the dirs gives us
a list of all available events.
