The logic that decides whether to idle the device is scattered across three functions. Almost all of the logic is in the function bfq_bfqq_may_idle, but (1) part of the decision is made in bfq_update_idle_window, and (2) the function bfq_bfqq_must_idle may switch off idling regardless of the output of bfq_bfqq_may_idle. In addition, both bfq_update_idle_window and bfq_bfqq_must_idle make their decisions as a function of parameters that are used, for similar purposes, also in bfq_bfqq_may_idle. This commit addresses these issues by moving all the logic into bfq_bfqq_may_idle. Signed-off-by: Paolo Valente <paolo.valente@linaro.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
