This patch warns about messages which are received from nodes who
already left the lockspace resource signaled by the cluster manager.
Before commit 489d8e559c ("fs: dlm: add reliable connection if
reconnect") there was a synchronization issue with the socket
lifetime and the cluster event of leaving a lockspace and other
nodes did not stop of sending messages because the cluster manager has a
pending message to leave the lockspace. The reliable session layer for
dlm use sequence numbers to ensure dlm message were never being dropped.
If this is not corrected synchronized we have a problem, this patch will
use the filter case and turn it into a WARN_ON_ONCE() so we seeing such
issue on the kernel log because it should never happen now.

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.
