Function signal_our_withdraw needs to work on file systems that have been partially frozen. To do this, it called flush_workqueue(gfs2_freeze_wq). This this wrong because it waits for *ALL* file systems to be unfrozen, not just the one we're withdrawing from. It should only wait for the targetted file system to be unfrozen. Otherwise it would wait until ALL file systems are thawed before signaling the withdraw. This patch changes signal_our_withdraw so it calls flush_work() for the target file system's freeze work (only) to be completed.

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.
