Registers fscache context for primary data blob. Also move the initialization of s_op and related fields forward, since anonymous inode will be allocated under the super block when registering the fscache context. Something worth mentioning about the cleanup routine. 1. The fscache context will instantiate anonymous inodes under the super block. Release these anonymous inodes when .put_super() is called, or we'll get "VFS: Busy inodes after unmount." warning. 2. The fscache context is initialized prior to the root inode. If .kill_sb() is called when mount failed, .put_super() won't be called when root inode has not been initialized yet. Thus .kill_sb() shall also contain the cleanup routine.

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.
