Patent ID: 7406694

Claim:
A method for tracking kernel resource usage comprising: generating a tag to charge a process allocated with kernel resources wherein generating a tag further comprises: determining whether a request for kernel resources is passed from an intermediate function using a worker thread; finding at least one link between the worker thread and the process; and, identifying the process that originated the request according to the found link between the worker thread and the process; determining whether the process is a kernel process; determining whether the process is a user process; flagging the tag with a kernel flag to indicate whether the process has been determined to be a kernel process, the flagging further comprising: generating a tag value to identify kernel resources allocated to a user process; saving a type of kernel resources allocated to the tag; and, saving a user process identifier to the tag to identify the process; flagging the tag with a user flag to indicate whether the process has been determined to be a user process based upon the determination step wherein the tag value and the type of kernel resources are saved in a first word of the tag, and the user process identifier is saved in a second word of the tag; determining whether the process is a first predefined process or a second predefined process; saving an identifier to the tag to identify whether the process is a first predefined process or a second predefined process based upon the determination step; determining whether the process has used more kernel usage than a threshold; and if the process kernel usage is above a threshold, aborting the process.
