When a queue is reset, the status response code returned from the reset operation is stored in the reset_rc field of the vfio_ap_queue structure representing the queue being reset. This field is later used to decide whether the queue should be passed through to a guest. If the reset_rc field is a non-zero value, the queue will be filtered from the list of queues passed through. When an adapter is deconfigured, all queues associated with that adapter are reset. That being the case, it is not necessary to filter those queues; so, if the status response code returned from a reset operation indicates the queue is deconfigured, the reset_rc field of the vfio_ap_queue structure will be set to zero so it will be passed through (i.e., not filtered).

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.
