This is the identity conversion. The workqueue "fg_wq" is used for running the FG algorithm periodically. It has been identity converted. It has multiple work items viz fg_periodic_work, fg_low_bat_work, fg_reinit_work, fg_work, fg_acc_cur_work and fg_check_hw_failure_work, which require execution ordering. Hence, a dedicated ordered workqueue has been used here. The WQ_MEM_RECLAIM flag has been set to guarantee forward progress under memory pressure.
