[PATCH v3 2/3] leaking_addresses: also skip canonical ftrace path

From: Ross Zwisler
Date: Fri Mar 10 2023 - 14:21:14 EST


From: Ross Zwisler <zwisler@xxxxxxxxxx>

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

scripts/leaking_addresses.pl only skipped this older debugfs path, so
let's add the canonical path as well.
