debugfs is currently severely broken virtually everywhere in the kernel where files are dynamically added and removed (see http://lkml.iu.edu/hypermail/linux/kernel/1506.1/02196.html for some details). In addition to that, debugfs is not namespace-aware. Instead of adding new debugfs entries, the whole infrastructure should be moved to netlink. This will fix the long standing problem of large buffers for debug tables and hard to parse text files.
