update_tg_cfs_*() propagate the impact of the attach/detach of an entity down into the cfs_rq hierarchy and must keep the sync with the current pelt window. Even if we can't sync child cfs_rq and its group se, we can sync the group se and its parent cfs_rq with current position in the PELT window. In fact, we must keep them sync in order to stay also synced with others entities and group entities that are already attached to the cfs_rq.

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.
