cpu_clock_sample_group() and cpu_timer_sample_group() are almost the same. Before the rename one called thread_group_cputimer() and the other thread_group_cputime(). Really intuitive function names. Consolidate the functions and also avoid the thread traversal when the thread group's accounting is already active.

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.
