Patch series "nilfs2: eliminate kmap and kmap_atomic calls". This series converts remaining kmap and kmap_atomic calls to use kmap_local, mainly in metadata files, and eliminates calls to these deprecated kmap functions from nilfs2. This series does not include converting metadata files to use folios, but it is a step in that direction. Most conversions are straightforward, but some are not: the checkpoint file, the inode file, and the persistent object allocator. These have been adjusted or rewritten to avoid multiple kmap_local calls or nest them if necessary, and to eliminate long waits like block I/O within the highmem mapping sections. This series has been tested in both 32-bit and 64-bit environments with varying block sizes. This patch (of 15): In the recovery function when mounting, nilfs_recovery_copy_block() uses the deprecated kmap_atomic(), so convert it to use kmap_local.

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.
