Subject: [PATCH AUTOSEL 5.1 016/141] f2fs: fix to avoid deadloop if data_flush is on

[ Upstream commit 040d2bb318d1aea4f28cc22504b44e446666c86e ]
As Hagbard Celine reported:

There is still deadloop in below condition:
d A
- do_writepages
- f2fs_write_node_pages
- f2fs_balance_fs_bg
- f2fs_sync_dirty_inodes
- f2fs_write_cache_pages
- mutex_lock(&sbi->writepages) -- lock once
- __write_data_page
- f2fs_balance_fs_bg
- f2fs_sync_dirty_inodes
- f2fs_write_data_pages
- mutex_lock(&sbi->writepages) -- lock again
Thread A Thread B
- do_writepages
- f2fs_write_node_pages
- f2fs_balance_fs_bg
- f2fs_sync_dirty_inodes
- .cp_task = current
- f2fs_sync_dirty_inodes
- .cp_task = current
- filemap_fdatawrite
- .cp_task = NULL
- filemap_fdatawrite
- f2fs_write_cache_pages
- enter f2fs_balance_fs_bg since .cp_task is NULL
- .cp_task = NULL
Change as below to avoid this:
- add condition to avoid holding .writepages mutex lock in path
of data flush
- introduce mutex lock sbi.flush_lock to exclude concurrent data
flush in background.
