If the network stack keeps a reference for too long, DRBD keeps references on a higher number of pages as a consequence. Fix all that by no longer relying on page reference counts dropping to an expected value. Instead, DRBD gives up its reference and lets the system handle everything else. While at it, remove the open-coded custom page pool mechanism and use the page_pool included in the kernel.

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.
