nr_spread_over tracks the number of instances where the difference between a scheduling entity's virtual runtime and the minimum virtual runtime in the runqueue exceeds three times the scheduler latency, indicating significant disparity in task scheduling. Commit that removed its usage:5e963f2bd: sched/fair: Commit to EEVDF cfs_rq->exec_clock was used to account for time spent executing tasks. Commit that removed its usage:5d69eca542sched: Unify runtime accounting across classes cfs_rq::nr_spread_over and cfs_rq::exec_clock are not used anymore in eevdf. Remove them from struct 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 reStructuredText 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.
