When userspace restarts during boot or upgrades it won't know about the offload driver's endpoint and connection mappings. iscsid will start by cleaning up the old session by doing a stop_conn call. Later, if we are able to create a new connection, we clean up the old endpoint during the binding stage. The problem is that if we do stop_conn before doing the ep_disconnect call offload, drivers can still be executing I/O. We then might free tasks from the under the card/driver. This moves the ep_disconnect call to before we do the stop_conn call for this case. It will then work and look like a normal recovery/cleanup procedure from the driver's point of view.

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.
