commit c26aa57202 upstream.
Current code matches subnqn and collapses all controllers to the
same subnqn to a single subsystem structure. This is good for
recognizing multiple controllers for the same subsystem. But with
the well-known discovery subnqn, the subsystems aren't truly the
same subsystem. As such, subsystem specific rules, such as no
overlap of controller id, do not apply. With today's behavior, the
check for overlap of controller id can fail, preventing the new
discovery controller from being created.
When searching for like subsystem nqn, exclude the discovery nqn
from matching. This will result in each discovery controller being
attached to a unique subsystem structure.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
