4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chao Yu <yuch...@huawei.com>
[ Upstream commit 64c74a7ab505ea40d1b3e5d02735ecab08ae1b14 ]
- 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.
