Abstract:
1. A method of handling a request from an application to an operating system to perform a file operation relative to a specific file, the method comprising the steps of: receiving the request to perform the file operation, wherein the request to perform the file operation causes a file look-up operation; attempting to perform the file look-up operation without suspending task execution by retrieving a file path corresponding to the specific file from a file system namespace cache; notifying the application that the file operation could not be performed without suspending task execution so that the application can redirect the request, if the file look-up operation could not be performed without suspending task execution because the file path is not stored in the file system namespace cache; and performing the file operation without suspending task execution if the file look-up operation could be performed without suspending task execution because the file path corresponding to the specific file is stored in the file system namespace cache.
