Subject: [PATCH 1/2] f2fs: fix to don't trigger writeback during recovery
Date: Sat, 26 May 2018 18:03:34 +0800	[thread overview]
Message-ID: <20180526100335.63001-1-yuchao0@huawei.com> (raw)

        - f2fs_balance_fs
         - f2fs_balance_fs_bg
          - sync_dirty_inodes

With data_flush mount option, during recovery, in order to avoid entering
above writeback flow, let's detect recovery status and do skip in
f2fs_balance_fs_bg.
