Linux kernel source tree
94ee8708c9
The NVMe PCI transport specification allows for completion queues to be shared by different submission queues. This patch allows a submission queue to keep track of the completion queue it is using with reference counting. As such, it can be ensured that a completion queue is not deleted while a submission queue is actively using it. This patch enables completion queue sharing in the pci-epf target driver. For fabrics drivers, completion queue sharing is not enabled as it is not possible as per the fabrics specification. However, this patch modifies the fabrics drivers to correctly integrate the new API that supports completion queue sharing.

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 reStructuredText 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.
