Linux kernel source tree

Until the base value for request service times gets finally computed for a bfq_queue, the inject limit for that queue does depend on the think-time state (short|long) of the queue. A timely update of the think time then guarantees a quicker activation or deactivation of the injection. Fortunately, the think time of a bfq_queue is updated in the same code path as the inject limit; but after the inject limit. This commits moves the update of the think time before the update of the inject limit. For coherence, it moves the update of the seek time too. Reported-by: Srivatsa S.

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.
