A bug was introduced in deadline_from_pos() while implementing the suggestion to use round_down() in the following code: pos -= bdev_offset_from_zone_start(rq->q->disk->part0, pos); This patch makes deadline_from_pos() use round_down() such that 'pos' is rounded down.

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.
