This patch adds a warn on if is_master() and dlm_is_removed() checks on invalid nodeid states that are probably not what the caller wants to do here. The is_master() function checking on r->res_nodeid is invalid when it is set to -1, whereas the dlm_is_removed() has a different meaning as "nodeid member" and also 0 is invalid. We run into these cases and this patch changes those cases as we never will run into them. There should be no functional changes as the condition should return the same result. However this patch signals now on caller level that there might be an "extra" case to handle here.

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.
