Quinn Tran 19bba55319 scsi: qla2xxx: Delete all sessions before unregister local nvme port 
[ Upstream commit c48f849d3f ]

Delete all sessions before unregistering local nvme port.  This allows nvme
layer to decrement all active rport count down to zero.  Once the count is
down to zero, nvme would call qla to continue with the npiv port deletion.

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.
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.
