摘要： The invention provides a system and method for dynamically unloading file system filters in a stacked-call-back model where filters are stacked one on top of the other to form a filter stack. A filter manager keeps track of the progress of each I/O operation and calls each filter in turn with the filter returning after it has completed processing the given operation. The filter manager dynamically unloads a filter (or an instance of a filter) that is positioned at any position in the filter stack in a reasonable amount of time while I/O operations are actively being processed. The filter/filter instance can be unloaded with outstanding I/O operations on the filter either hosted by the filter or pended by other filters. I/O operations are canceled, completed or drained in order to unload the filter or filter instance. A filter may veto the unloading of the filter.

摘要： A model in which filter drivers are managed to receive callbacks for I/O requests in which the filter drivers have registered an interest. Per-volume instances of filter drivers register with a filter manager for pre-callbacks (for I/O to the file system) and post-callbacks (for I/O from the file system), and identify which I/O requests (e.g., create, read, write) they are registering to receive callbacks. The filter manager orders the instances for callbacks. When an I/O request is received, the filter manager converts the I/O request to callback data and calls the interested filters in the callback order, whereby the filter instances can process the I/O data. As the request returns from the file system, filters desiring post callbacks are called in the reverse order. Efficient context management for the filters and other functions, such as non-reentrant file I/O, are also provided by the model.

摘要： Systems and methods that create a virtual name space of Universal Naming Convention (UNC) over a local file system (e.g., drive letter based names), via employing a UNC provider and filter arrangement that changes a name in the file object to reparse it to a volume where the local file exists. A name in the file object is changed to a local name (e.g., morphed name); subsequently reparsed and forwarded to a Name Space Owner component (NSO). As such, a request can originate from a UNC stack and reparsed on the local stack. The name space is presented to an application in UNC format, while the underlying file write occur in the file system.
摘要翻译：通过本地文件系统（例如，基于驱动器号的名称）创建通用命名约定（UNC）的虚拟名称空间的系统和方法，通过使用UNC提供程序和过滤器布置来更改文件对象中的名称以将其重新分解为本地文件存在的卷。文件对象中的名称更改为本地名称（例如，变形名称）; 随后重新编译并转发给名称空间所有者组件（NSO）。因此，请求可以源自UNC堆栈，并在本地堆栈上重新生成。名称空间以UNC格式呈现给应用程序，而文件系统中发生底层文件写入。
