It makes no sense to have sysfs-related routines be responsible for properly initialising the fs_info pointer of struct btrfs_fs_device. Instead this can be streamlined by making it the responsibility of btrfs_init_devices_late to initialize it. That function already initializes fs_info of every individual device in btrfs_fs_devices. As far as clearing it is concerned it makes sense to move it to close_fs_devices. That function is only called when struct btrfs_fs_devices is no longer in use - either for holding seeds or main devices for a mounted filesystem.

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.
