Abstract: Method and apparatus for atomic file look-up. An atomic look-up operation allows an application to find out whether a file is opened atomically based on whether or not the file path is present in a file system namespace cache. If not, the file open request can be redirected, avoiding or minimizing impacts to the scheduling of various operations involved in executing an application. The request can be redirected by the application to a process that includes blocking point handling. An operating system according to the present invention includes a file system including a file system namespace, and an operating system kernel is operatively connected to the file system. The operating system kernel includes the file system namespace cache and the atomic look-up operation.

Abstract: An embodiment relates generally to a method of preventing resource access conflicts in a software component. The method includes intercepting a lock operation in the software component and testing an associated lock type of the lock operation against a set of rules. The method also includes determining an action based on the associated lock type conflicting one of the rules of the set of rules.

Abstract: Method and apparatus for handling communication requests at a server without context switching. An application protocol subsystem and protocol modules are disposed within an operating system kernel at a server. The protocol subsystem creates an “in-kernel” protocol stack that stores information regarding application protocol requests, such as HTTP and FTP requests, in a kernel request structure. A user space application can then continue execution while the operating system responds to the application protocol request without context switching. In this way, application protocol requests received over a network are handled and responded to by the server without causing a context switch.
