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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
