Move the code for reading from a checkpoint entry that is performed in nilfs_attach_checkpoint() to the cpfile side, and make the page mapping local and temporary. And use kmap_local instead of kmap to access the checkpoint entry page. In order to load the ifile inode information included in the checkpoint entry within the inode lock section of nilfs_ifile_read(), the newly added checkpoint reading method nilfs_cpfile_read_checkpoint() is called indirectly via nilfs_ifile_read() instead of from nilfs_attach_checkpoint().

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.
