lpfc was changing the private pointer that is set/maintained by the nvme_fc transport. This caused two issues: a) the transport, on teardown may erroneous attempt to free whatever address was set; and b) lfpc uses any value set in lpfc_nvme_fcp_abort() and assumes its a valid io request. Correct issue by properly defining a context structure for lpfc. Lpfc also updated to clear the private context structure on io completion. Since this bug caused scrutiny of the way lpfc moves local request structures between lists, also cleaned up list_del()'s to list_del_inits()'s. This is a nvme-specific bug. The patch was cut against the linux-block tree, for-4.12/block tree. It should be pulled in through that tree.

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.
