Before deciding to pull tasks when using asymmetric packing of tasks, on some architectures (e.g., x86) it is necessary to know not only the state of dst_cpu but also of its SMT siblings. The decision to classify a candidate busiest group as group_asym_packing is done in update_sg_lb_stats(). Give this function access to the scheduling domain statistics, which contains the statistics of the local group.

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.
