gnet_stats_add_basic() and gnet_stats_add_queue() add up the statistics so they can be used directly for both the per-CPU and global case. gnet_stats_add_queue() copies either Qdisc's per-CPU gnet_stats_queue::qlen or the global member. The global gnet_stats_queue::qlen isn't touched in the per-CPU case so there is no need to consider it in the global-case. In the per-CPU case, the sum of global gnet_stats_queue::qlen and the per-CPU gnet_stats_queue::qlen was assigned to sch->q.qlen and sch->qstats.qlen. Now both fields are copied individually.

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.
