[PATCH 0/5] perf: Have perf become tracefs aware

[Steven Rostedt]

As I'm trying to move the tracing directory from debugfs, perf needs to
be aware of this as system admins will now be able to mount the tracing
directory without needing to mount debugfs. This patch series addresses
this and makes perf aware of tracefs.

I based this series on a recent tip branch: perf/core.

You can also get this series from my repo as stated below.
