For FLUSH_LIMIT flushers we really can only allocate chunks and flush delayed inode items, everything else is problematic. I added a bunch of new states and it lead to weirdness in the FLUSH_LIMIT case because I forgot about how it worked. So instead explicitly declare the states that are ok for flushing with FLUSH_LIMIT and use that for our state machine. Then as we add new things that are safe we can just add them to this list.

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.
