Linux kernel source tree

Now that the driver has gone to a normal ref interface (with no odd logic) the discovery logic needs to be updated to reworked so that it properly takes references when it should and give them up when it should. Rework the driver for the following get/put model: - Move gets to just before an I/O is issued. Add gets for places where an I/O was issued without one. - Ensure that failures from lpfc_nlp_get() are handled by the driver. - Check and fix the placement of lpfc_nlp_puts relative to io completions. Note: some of these paths may not release the reference on the exact io completion as the reference is held as the code takes another step in the discovery thread and which may cause another io to be issued. - Rearrange some code for error processing and calling lpfc_nlp_put. - Fix some places of incorrect reference freeing that was causing the premature releasing of the structure. - Nvmet plogi handling performs unreg_rpi's. The reference counts were unbalanced resulting in premature node removal. In some cases this caused loss of node discovery. Corrected the reftaking around nvmet plogis. Nodes that experience devloss now get released from the node list now that there is a proper reference taking.

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.
