| |
- f2fs_fill_super - recover_fsync_data - recover_data - del_fsync_inode - iput - iput_final - write_inode_now - f2fs_write_inode - 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.
