The current way to store the required private data needed to access various debugfs entries is to alloc them on the fly, share them within the entries that need to access them, and finally have one entry free that data upon closing. This leads to hard to maintain code, and is very error-prone. This commit stores all debugfs related data in the same place, making sure this is allocated only when the debugfs directory is successfully created, so that we don't waste memory when we don't use this feature.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
