commit2ea80b039bupstream. Since 5.14-rc1, NUMA events will only be folded from per-CPU statistics to per zone and global statistics when the user actually needs it. Currently, the kernel has performs the fold operation when reading /proc/vmstat, but does not perform the fold operation in /proc/zoneinfo. This can lead to inaccuracies in the following statistics in zoneinfo: - numa_hit - numa_miss - numa_foreign - numa_interleave - numa_local - numa_other Therefore, before printing per-zone vm_numa_event when reading /proc/zoneinfo, we should also perform the fold operation.

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.
