workqueue_attrs can be used for both workqueues and worker_pools. However, some fields, currently only ->ordered, only apply to workqueues and should be cleared to the default / invalid values. Currently, an unbound workqueue explicitly clears attrs->ordered in get_unbound_pool() after copying the source workqueue attrs, while per-cpu workqueues rely on the fact that zeroing on allocation gives us the desired default value for pool->attrs->ordered. This is fragile. Let's add wqattrs_clear_for_pool() which clears attrs->ordered and is called from both init_worker_pool() and get_unbound_pool(). This will ease adding more workqueue-only attrs fields. In get_unbound_pool(), pool->node initialization is moved upwards for readability. This shouldn't cause any 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.
