The workqueue fs_info->scrub_worker would go ordered workqueue if it's a device replace operation. However the scrub is relying on multiple workers to do data csum verification, and we always submit several read requests in a row. Thus there is no need to use ordered workqueue just for dev-replace. We have extra synchronization (the main thread will always submit-and-wait for dev-replace writes) to handle it for zoned devices.

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.
