Use library helper memcpy_page() to copy source page into destination instead of having duplicate code in copy_to_nullb() & copy_from_nullb(). In copy_from_nullb() also replace the memset call with zero_user(). Use library helper memset_page() to set the buffer to 0xFF instead of having duplicate code. This also removes deprecated API kmap_atomic() from copy_to_nullb() copy_from_nullb() and nullb_fill_pattern(), from :include/linux/highmem.h: "kmap_atomic - Atomically map a page for temporary usage - Deprecated!"

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.
