During f2fs_write_checkpoint(), once we failed in f2fs_flush_nat_entries() or do_checkpoint(), metadata of filesystem such as prefree bitmap, nat/sit version bitmap won't be recovered, it may cause f2fs image to be inconsistent, let's just set CP error flag to avoid further updates until we figure out a scheme to rollback all metadatas in such condition.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
