[PATCH 0/4] ref_tracker: register debugfs files for each ref_tracker_dir

[Jeff Layton]

I had previously sent some patches to add debugfs files for the net
namespace refcount trackers, but Andrew convinced me to make this more
generic and better-integrated into the ref_tracker infrastructure.

This adds a new ref_tracker_dir_debugfs() call that subsystems can call
to finalize the name of their dir and register a debugfs file for it.
The last two patches add these calls for the netns and netdev
ref_trackers.
