Someone else told me about doing this too. I'll take a look at it.

Well, if I switch to using kernfs, I expect we should ignore this
version as well, as I would think it would make this series obsolete.

Also, if that's the case, I guess I could keep all the "tracefs" code
in kernel/tracing and not place it in the fs/ directory? Kind of like
what cgroups does.
