mainlining shenanigans
428b448ee7
This patch implements the same basic fix for event rings as the
previous one does for channels.
The result of issuing an event ring control command should be that
the event ring changes state. If enabled, a completion interrupt
signals that the event ring state has changed. This interrupt is
enabled by gsi_evt_ring_command() and disabled again after the
command has completed (or we time out).
There is a window of time during which the command could complete
successfully without interrupting. This would cause the event ring
to transition to the desired new state.
So whether a event ring command ends via completion interrupt or
timeout, we can consider the command successful if the event ring
has entered the desired state (and a failure if it has not,
regardless of the cause).

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.
