When a gfs2 file system is withdrawn it does iput on its journal to allow recovery from another cluster node. If it's unable to get a replacement inode for whatever reason, the journal descriptor would still be pointing at the evicted inode. So when unmount clears out the list of journals, it would do a second iput referencing the pointer. To avoid this, set the inode pointer to NULL.

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.
