Gregory Nutt 360539afac Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is only a single, hard-allocated holder structure. This is problem because in sem_wait() the holder is released, but needs to remain in the holder container until sem_restorebaseprio() is called. The call to sem_restorebaseprio() must be one of the last things the sem_wait() does because it can cause the task to be suspended. If in sem_wait(), a new task gets the semaphore count then it will fail to allocate the holder and will not participate in priority inheritance. This fix is to add two hard-allocated holders in the sem_t structure: One of the old holder and one for the new holder.		2017-03-10 09:30:15 -06:00
