It is inappropriate to use sysctl_vfs_cache_pressure here. The sysctl is documented as: This percentage value controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects. So, simplify result of rpcauth_cache_shrink_count() to "return number_cred_unused;".

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 reStructuredText 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.
