conntrack uses the bounded system_long_wq workqueue for its works that don't have to run on the cpu they have been queued. Using bounded workqueue prevents the scheduler to make smart decision about the best place to schedule the work. This patch replaces system_long_wq with system_power_efficient_wq. the work stays bounded to a cpu by default unless the CONFIG_WQ_POWER_EFFICIENT is enable. In the latter case, the work can be scheduled on the best cpu from a power or a performance point of view.

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.
