mainlining shenanigans

Now, we invoke f2fs_mark_inode_dirty_sync() to make an inode dirty in advance of creating a new node page for the inode. By this, some inodes whose node page is not created yet can be linked into the global dirty list. If the checkpoint is executed at this moment, the inode will be written back by writeback_single_inode() and finally update_inode_page() will fail to detach the inode from the global dirty list because the inode doesn't have a node page. The problem is that the inode's state in VFS layer will become clean after execution of writeback_single_inode() and it's still linked in the global dirty list of f2fs and this will cause a kernel panic. So, we will prevent the newly created inode from being dirtied during the FI_NEW_INODE flag of the inode is set. We will make it dirty right after the flag is cleared.

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.
