Mute the periodic "stalled pool shutdown" warning if the page pool is visible to user space. Rolling out a driver using page pools to just a few hundred hosts at Meta surfaces applications which fail to reap their broken sockets. Obviously it's best if the applications are fixed, but we don't generally print warnings for application resource leaks. Admins can now depend on the netlink interface for getting page pool info to detect buggy apps. While at it throw in the ID of the pool into the message, in rare cases (pools from destroyed netns) this will make finding the pool with a debugger easier.

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.
