Previously, f2fs_checkpoint.checksum_offset points fixed position of f2fs_checkpoint structure: "#define CP_CHKSUM_OFFSET 4092" It is unnecessary, and it breaks the consecutiveness of nat and sit bitmap stored across checkpoint park block and payload blocks. This patch allows f2fs to handle unfixed .checksum_offset. In addition, for the case checksum value is stored in the middle of checkpoint park, calculating checksum value with superposition method like we did for inode_checksum.

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.
