wq_adjust_max_active() needs to activate work items after max_active is increased. Previously, it did that by visiting each pwq once activating all that could be activated. While this makes sense with per-pwq nr_active, nr_active will be shared across multiple pwqs for unbound wqs. Then, we'd want to round-robin through pwqs to be fairer. In preparation, this patch makes wq_adjust_max_active() round-robin pwqs while activating. While the activation ordering changes, this shouldn't cause user-noticeable behavior changes.

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.
