[merged] selftests-use-canonical-ftrace-path.patch removed from -mm tree

[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: selftests: use canonical ftrace path
has been removed from the -mm tree.  Its filename was
     selftests-use-canonical-ftrace-path.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: selftests: use canonical ftrace path
Date: Mon, 13 Mar 2023 15:17:43 -0600

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 few spots in tools/testing/selftests still refer to this older debugfs
path, so let's update them to avoid confusion.
