Our QE team during automated API testing hit deadlock in ZFS, caused by lock order reversal. From one side dsl_sync_task_sync() locks dp_config_rwlock as writer and calls spa_sync_props(), which waits for spa_props_lock. From another spa_prop_get() locks spa_props_lock and then calls dsl_pool_config_enter(), trying to lock dp_config_rwlock as reader. This patch makes spa_prop_get() lock dp_config_rwlock before spa_props_lock, making the order consistent.
