This undocumented macro seems to represent "a small amount of time". Sometimes it is used as-is, some times it is multiplied by 5 for no obvious reason. It does not appear that there is any connection between the different places it is used - they all just want a short period for different purposes and of different durarions. So discard CFS_TICK and lets each use-site just use whatever number of jiffies seems appropriate in that case.

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.
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.
