In update_sd_pick_busiest(), when comparing two sched groups that are both of type group_misfit_task, we currently consider the new group as busier than the current busiest group even if the new group has the same misfit task load as the current busiest group. We can avoid some unnecessary writes if we instead only consider the newest group to be the busiest if it has a higher load than the current busiest. This matches the behavior of other group types where we compare load, such as two groups that are both overloaded. Let's update the group_misfit_task type comparison to also only update the busiest group in the event of strict inequality.

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.
