Upon an increment attempt of the injection limit, the latter is constrained not to become higher than twice the maximum number max_rq_in_driver of I/O requests that have happened to be in service in the drive. This high bound allows the injection limit to grow beyond max_rq_in_driver, which may then cause max_rq_in_driver itself to grow. However, since the limit is incremented by only one unit at a time, there is no need for such a high bound, and just max_rq_in_driver+1 is enough.

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.
