Switch to using system_percpu_wq because system_wq is going away as part of a workqueue restructuring. Currently if a user enqueues a work item using schedule_delayed_work() the used workqueue is "system_wq" (per-cpu workqueue) while queue_delayed_work() uses WORK_CPU_UNBOUND (used when a CPU is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use of WORK_CPU_UNBOUND again. This lack of consistency cannot be addressed without refactoring the API.

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 reStructuredText 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.
