Andreas Gruenbacher abea81e6a7 gfs2: Fix "ignore unlock failures after withdraw" 
[ Upstream commit 5d92311119 ]

Commit 3e11e53041 tries to suppress dlm_lock() lock conversion errors
that occur when the lockspace has already been released.

It does that by setting and checking the SDF_SKIP_DLM_UNLOCK flag.  This
conflicts with the intended meaning of the SDF_SKIP_DLM_UNLOCK flag, so
check whether the lockspace is still allocated instead.

(Given the current DLM API, checking for this kind of error after the
fact seems easier that than to make sure that the lockspace is still
allocated before calling dlm_lock().  Changing the DLM API so that users
maintain the lockspace references themselves would be an option.)

README 

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.
