We've got a few issues that all boil down to the fact that we have one
list of pending work items, yet two different types of workers to
serve them. This causes some oddities around workers switching type and
even hashed work vs regular work on the same bounded list.
Just separate them out cleanly, similarly to how we already do
accounting of what is running. That provides a clean separation and
removes some corner cases that can cause stalls when handling IO
that is punted to io-wq.
Fixes: ecc53c48c1 ("io-wq: check max_worker limits if a worker transitions bound state")

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.
