Introduce a new struct nvme_ns_head that holds information about an actual namespace, unlike struct nvme_ns, which only holds the per-controller namespace information. For private namespaces there is a 1:1 relation of the two, but for shared namespaces this lets us discover all the paths to it. For now only the identifiers are moved to the new structure, but most of the information in struct nvme_ns should eventually move over. To allow lockless path lookup the list of nvme_ns structures per nvme_ns_head is protected by SRCU, which requires freeing the nvme_ns structure through call_srcu.

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.
