Implement functions to allow the cache backend to add or remove a cache:
(1) Declare a cache to be live:
int fscache_add_cache(struct fscache_cache *cache,
const struct fscache_cache_ops *ops,
void *cache_priv);
Take a previously acquired cache cookie, set the operations table and
private data and mark the cache open for access.
(2) Withdraw a cache from service:
void fscache_withdraw_cache(struct fscache_cache *cache);
This marks the cache as withdrawn and thus prevents further
cache-level and volume-level accesses.

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.
