Add support for plugging in passthrough path. When plugging is enabled, the requests are added to a plug instead of getting dispatched to the driver. And when the plug is finished, the whole batch gets dispatched via ->queue_rqs which turns out to be more efficient. Otherwise dispatching used to happen via ->queue_rq, one request at a time.

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.
