From 19863f5f4cefad1a868dac830e06d7c53cb93330 Mon Sep 17 00:00:00 2001 From: Kaixu Xia Date: Thu, 31 Mar 2016 13:19:41 +0000 Subject: [PATCH] writeback: fix the wrong congested state variable definition commit c877ef8ae7b8edaedccad0fc8c23d4d1de7e2480 upstream. The right variable definition should be wb_congested_state that include WB_async_congested and WB_sync_congested. So fix it.
