Btrfs only allowed attributes to be exposed in debug/. Let's let other groups be created by making debug its own kobject. This also makes the per-fs debug options separate from the global features mount attributes. This seems to be needed as sysfs_create_files() requires const struct attribute * while sysfs_create_group() can take struct attribute *. This seems nicer as per file system, you'll probably use to_fs_info().

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.
