| Subject: writeback: fix the wrong congested state variable definition |
| |
| From: Kaixu Xia <xiakaixu@huawei.com> |
| |
| commit c877ef8ae7b8edaedccad0fc8c23d4d1de7e2480 upstream. |
| |
| The right variable definition should be wb_congested_state that |
| include WB_async_congested and WB_sync_congested. So fix it. |
