When a node moves to NPR state due to a device recovery event, the nlp_fc4_types in the node are cleared. An ADISC received for a node in the NPR state triggers an ADISC. Without fc4 types being known, the calls to register with the transport are no-op'd, thus no additional references are placed on the node by transport re-registrations. A subsequent RSCN could trigger another unregister request, which will decrement the reference counts, leading to the ref count hitting zero and the node being freed while futher discovery on the node is being attempted by the RSCN event handling. Fix by skipping the trigger of an ADISC when in NPR state. The normal ADISC process will kick off in the regular discovery path after receiving a response from name server.

README
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.
