We need to avoid unconditionally calling balance_dirty_pages_ratelimited as it could wait for some reason. Use balance_dirty_pages_ratelimited_flags with the BDP_ASYNC in case the buffered write is nowait, returning EAGAIN eventually. It also moves the function after the again label. This can cause the function to be called a bit later, but this should have no impact in the real world.

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.
