This is a bus-like on top of XenStore. It will look for advertised ParaVirtualized devices and initialize them by producing XenBus protocol. Change in V4: - Replace the license by the commonly used file header text. - Clean XenBus.h header (remove copyright that does not belong to the file anymore; and rewrite the brief description of the file) - Fix description on the function Change in V3: - Insert to ChildList later, once populated. - Remove XENBUS_XENSTORE_NODE macro. - add comment to XenBusAddDevice and XenBusEnumerateBus about concurrency calls. - Add a description to the introduced member to the protocol. Change in V2: - comment, file header - Fix comment style - Error handling in the main init function - coding style - Fix error path in add device. Origin: FreeBSD 10.0 License: This patch adds XenBus.c which is under the MIT licence.
