Introduce a data structure named pvcalls_bedata. It contains pointers to the command ring, the event channel, a list of active sockets and a list of passive sockets. Lists accesses are protected by a spin_lock. Introduce a waitqueue to allow waiting for a response on commands sent to the backend. Introduce an array of struct xen_pvcalls_response to store commands responses. Introduce a new struct sock_mapping to keep track of sockets. In this patch the struct sock_mapping is minimal, the fields will be added by the next patches. pvcalls_refcount is used to keep count of the outstanding pvcalls users. Only remove connections once the refcount is zero. Implement pvcalls frontend removal function. Go through the list of active and passive sockets and free them all, one at a time.

README
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.
