[ Upstream commit 307af6c879377c1c63e71cbdd978201f9c7ee8df ] Use the fact that entries with elevated refcount are not removed from the hash and just move removal of the entry from the hash to the entry freeing time. When doing this we also change the generic code to hold one reference to the cache entry, not two of them, which makes code somewhat more obvious.

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.
