How do you support Linux Extensions like - SysV IPC/cgroups/inotiy/futext/readahead/udev etc?

Our level of support is posix 1003.1, 1003.1b and 1003.1c . In addition, the POSIX that we provide will automatically be able to take advantage of many of the real-time features from the specific OS Abstractor component for a target OS. OS Abstractor module provide the universal OS interfaces and OS features for many OS.
