Included in the current storvsc driver for Hyper-V is the ability to access luns on an FC fabric via a virtualized fiber channel adapter exposed by the Hyper-V host. The driver also attaches to the FC transport to allow host and port names to be published under /sys/class/fc_host/hostX. Current customer tools running on the VM require that these names be available in the well known standard location under fc_host/hostX. This patch stubs in an rport per fc_host and sets its rport role as FC_PORT_ROLE_FCP_DUMMY_INITIATOR to indicate to the fc_transport that it is a pseudo rport in order to scan the scsi stack via echo "- - -" > /sys/class/scsi_host/hostX/scan.

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.
