Linux kernel source tree
2be2cd5287
In order to test queue number changes we need to make sure that the host reconnects. Because only when the host disconnects from the target the number of queues are allowed to change according the spec. The initial idea was to disable and re-enable the ports and have the host wait until the KATO timer expires, triggering error recovery. Though the host would see a DNR reply when trying to reconnect. Because of the DNR bit the connection is dropped completely. There is no point in trying to reconnect with the same parameters according the spec. We can force to reconnect the host is by deleting all controllers. The host will observe any newly posted request to fail and thus starts the error recovery but this time without the DNR bit set.

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.
