[git:media_stage/master] media: visl: use canonical ftrace path
This is an automatic generated email to let you know that the following patch were queued: Subject: media: visl: use canonical ftrace path Author: Ross Zwisler Date:Tue Aug 29 14:46:01 2023 -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 Update the visl decoder driver documentation to use this tracefs path.
