Subject[PATCH 0/9] use canonical ftrace path whenever possible
Date
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

There are many places where this older debugfs path is still used in
code comments, selftests, examples and tools, so let's update them to
avoid confusion.

I've broken up the series as best I could by maintainer or directory,
and I've only sent people the patches that I think they care about to
avoid spamming everyone.

Ross Zwisler (9):
tracing: always use canonical ftrace path
bpf: use canonical ftrace path
selftests/bpf: use canonical ftrace path
perf docs: use canonical ftrace path
tools/power: use canonical ftrace path
selftests: use canonical ftrace path
tools/virtio: use canonical ftrace path
leaking_addresses: also skip canonical ftrace path
tools/kvm_stat: use canonical ftrace path
