In a link bounce scenario, a condition can occur where the discovery engine swaps an ndlp structure (address change for an nport). While the swap was successfully executed by the discovery engine, the driver did not properly detect a change in the ndlp bound to the nvme rport. This error resulted in the nvme host transport issuing an IO to the correct nvme rport, but the lpfc driver addressed a ndlp with an NLP_UNUSED status and failed the io. This resulting it it looking like there were missing namespaces and applications failed due to io errors. To fix, in lpfc_nvme_register_rport, rework the "rebind" case to break the nvme rport<->ndlp association when the ndlp already has an nrport. Then rebind the rport to the correct ndlp data and backpointers.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
