Since select_idle_sibling() can place a task anywhere on a socket, comparing loads between individual CPU cores makes no real sense for deciding whether to do an affine wakeup across sockets, either. Instead, compare the load between the sockets in a similar way the load balancer and the numa balancing code do.

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.
