Before this patch, when a node withdrew a gfs2 file system, it wrote a (clean) unmount log header. That's wrong. You don't want to write anything to the journal once you're withdrawn because that's acknowledging that the transaction is complete and the journal is in good shape, neither of which may be a valid assumption when the file system is withdrawn. This is especially true if the withdraw was caused due to io errors writing to the journal in the first place. The best course of action is to leave the journal "as is" until it may be safely replayed during journal recovery, regardless of whether it's done by this node or another.

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.
