Lines Matching full:mutex

5 a mutex wait directed graph, and then looks for a cycle in this graph. This
14 program will dump the cycle of mutexes, dump the stack traces where each mutex
21 Since this traces all mutex lock and unlock events and all thread creation
32 For recursive mutexes, lock() is called multiple times on the same mutex.
33 However, there is no way to determine if a mutex is a recursive mutex
34 after the mutex has been created. As a result, this tool will not find
35 potential deadlocks that involve only one mutex.
