Linux kernel source tree
The stats counters are now used for things like counting the VMA bytes during page faults. During workload execution, the counter value can grow fast and easily reach the atomic int limit, in which case it overflows. To make this less likely to happen, push the limit by switching to 64b atomic to store the counter value. Overhead is very small as there are only 3 stat entries per GT as of now, and stats are only enabled with CONFIG_DEBUG_FS.

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.
