Abstract: A method and structure for OS event notification, including a central processing unit (CPU) and a memory including instructions for an event notification mechanism for monitoring operating system events in an operating system (OS) being executed by the CPU. The OS includes a kernel having a plurality of kernel subcomponents that provide services to one or more applications executing in the OS in a user mode, using system calls to the kernel. The OS event notification mechanism is capable of monitoring events within the kernel, at a level below the user mode level. The OS event notification mechanism includes Application Program Interfaces (APIs) that are standard for the OS.

Abstract: A method and structure for notifying operating system events, includes standard filesystem interfaces provided for event consumers to use for one or more of registering for event notifications of a set of events, receiving an event notification when each event occurs, and getting details of events that have occurred.

Abstract: System, method and computer program product for supporting a plurality of Access Control List types for a file system in an operating system in a data processing system. An Access Control List supporting system for managing access to a file system in a data processing system has at least one file system in an operating system of the data processing system, and an Access Control List management framework in the operating system and external to the at least one file system for managing access to the at least one file system. The Access Control List supporting system of the invention removes ACL management and access check-related functions from the at least one file system to an external Access Control List management framework, thus enabling an operating system to support a plurality of Access Control List types using the same Access Control List management framework and enabling new Access Control List types to be added to the operating system dynamically while the operating system is running.
