Andreas Gruenbacher deb016c166 gfs2: No more self recovery
When a node withdraws and it turns out that it is the only node that has
the filesystem mounted, gfs2 currently tries to replay the local journal
to bring the filesystem back into a consistent state.  Not only is that
a very bad idea, it has also never worked because gfs2_recover_func()
will refuse to do anything during a withdraw.

However, before even getting to this point, gfs2_recover_func()
dereferences sdp->sd_jdesc->jd_inode.  This was a use-after-free before
commit 04133b607a ("gfs2: Prevent double iput for journal on error")
and is a NULL pointer dereference since then.

Simply get rid of self recovery to fix that.

Fixes: 601ef0d52e ("gfs2: Force withdraw to replay journals and wait for it to finish")

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.
