Abstract
Described are techniques synchronizing processing of at least two code threads. A first thread executing in user space is provided. A second thread executing in kernel space is provided. A global mutex lock is provided for synchronizing processing between said first thread and said second thread. One of said first thread and said second thread holds the global mutex lock and is identified as a current owner of the global mutex lock. The other of said first thread and said second thread requests the global mutex lock and is blocked until the current owner of the global mutex lock releases the global mutex lock. The global mutex lock is held by at most one thread at a point in time and is identified as the current owner.
