From 2abfcd293b79baf62895894fa3ea2386ffbe6338 Mon Sep 17 00:00:00 2001 From: Ross Zwisler Date: Wed, 25 Jan 2023 14:32:51 -0700 Subject: docs: ftrace: always 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 Many parts of Documentation still reference this older debugfs path, so let's update them to avoid confusion.
