Before this patch, function gfs2_freeze would loop forever if the filesystem it tries to freeze is withdrawn. That's because function gfs2_lock_fs_check_clean tries to enqueue the glock of the journal and the gfs2_glock returns -EIO because you can't enqueue a journaled glock after a withdraw. Move the check for file system withdraw inside the loop so that the loop can end when withdraw occurs.

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.
