Implement the accept command by calling inet_accept. To avoid blocking in the kernel, call inet_accept(O_NONBLOCK) from a workqueue, which get scheduled on sk_data_ready (for a passive socket, it means that there are connections to accept). Use the reqcopy field to store the request. Accept the new socket from the delayed work function, create a new sock_mapping for it, map the indexes page and data ring, and reply to the other end. Allocate an ioworker for the socket. Only support one outstanding blocking accept request for every socket at any time. Add a field to sock_mapping to remember the passive socket from which an active socket was created.

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.
