Right now io_wq allocates one io_wqe per NUMA node. As io_wq is now bound to a task, the task basically uses only the NUMA local io_wqe, and almost never changes NUMA nodes, thus, the other wqes are mostly unused. Allocate just one io_wqe embedded into io_wq, and uses all possible cpus (cpu_possible_mask) in the io_wqe->cpumask.

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.
