Darian Leung 1625a3aae2 freertos: Fix event group task list race condition ... FreeRTOS synchronization primitives (e.g., queues, eventgroups) use various event lists (i.e., task lists) to track what tasks are blocked on a current primitive. Usually these event lists are accessed via one of the event lists functions (such as vTask[PlaceOn|RemoveFrom]UnorderedEventList()), which in turn ensure that the global task list spinlock (xTaskQueueMutex) is taken when accessing these lists. However, some functions in event_groups.c manually traverse their event lists. Thus if a tick interrupt occurs on another core during traversal and that tick interrupt unblocks a task on the event list being traversed, the event list will be corrupted. This commit modifies the following event_groups.c functions so that they take the global task list lock before traversing their event list. - xEventGroupSetBits() - vEventGroupDelete()		2022-06-30 20:12:26 +08:00
