f2fs: fix fs corruption due to zero inode page
This patch fixes the following scenario.
- f2fs_create/f2fs_mkdir - write_checkpoint
- f2fs_mark_inode_dirty_sync - block_operations
- f2fs_lock_all
- f2fs_sync_inode_meta
- f2fs_unlock_all
- sync_inode_metadata
- f2fs_lock_op
- f2fs_write_inode
- update_inode_page
- get_node_page
return -ENOENT
- new_inode_page
- fill_node_footer
- f2fs_mark_inode_dirty_sync
- ...
- f2fs_unlock_op
- f2fs_inode_synced
- f2fs_lock_all
- do_checkpoint
In this checkpoint, we can get an inode page which contains zeros having valid
node footer only.
