I'm getting a bit lost searching through the git history of these
functions. Why is it safe to delete these functions? Where did the old
user that required find_tracing_dir() to mount debugfs disappear to?

The code to do the mount of debugfs/tracefs when perf starts appears
to have been around for years. Is the mounting operation of
find_tracing_dir() just dead code?
