Before this patch, function gfs2_ail1_start_one would return any errors it received from write_cache_pages (except -EBUSY) but it did not withdraw. Since function gfs2_ail1_flush just checks for the bad return code and loops, the loop might potentially never end. This patch adds some logic to allow it to exit the loop and withdraw properly when errors are received from write_cache_pages.

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.
