    Abstract: A method and an apparatus for priority donations among different processes are described. A first process running with a first priority may receive a request from a second process running with a second priority to perform a data processing task for the second process. A dependency relationship may be identified between the first process and a third process running with a third priority performing separate data processing task. The dependency relationship may indicate that the data processing task is to be performed via the first process subsequent to completion of the separate data processing task via the third process. The third process may be updated with the second priority to complete the separate data processing task. The first process may perform the data processing task with the second priority for the second process.
