There are two copies of cq_overflow, shared with userspace and internal cached one. It was needed for DRAIN accounting, but now we have yet another knob to tune the accounting, i.e. cq_extra, and we can throw away the internal counter and just increment the one in the shared ring. If user modifies it as so never gets the right overflow value ever again, it's its problem, even though before we would have restored it back by next overflow.

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.
