Write-back throttling (WBT) enables QUEUE_FLAG_STATS on the request queue. But WBT does not make sense for passthrough io, so skip QUEUE_FLAG_STATS processing. Also skip rq_qos_issue/done for passthrough io. Overall, the change gives ~11% hike in peak performance.

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.
