This commit introduces a global cache replacement (instead of per-client
cleanup).
If one bufio client uses the cache heavily and another client is not using
it, we want to let the first client use most of the cache. The old
algorithm would partition the cache equally betwen the clients and that is
sub-optimal.
For cache replacement, we use the clock algorithm because it doesn't
require taking any lock when the buffer is accessed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
