10436adf9diomap_dio_zero() uses a custom allocated memory of zeroes for padding zeroes. This was a temporary solution until there was a way to request a zero folio that was greater than the PAGE_SIZE. Use largest_zero_folio() function instead of using the custom allocated memory of zeroes. There is no guarantee from largest_zero_folio() function that it will always return a PMD sized folio. Adapt the code so that it can also work if largest_zero_folio() returns a ZERO_PAGE. Signed-off-by: Pankaj Raghav <p.raghav@samsung.com> Reviewed-by: Darrick J.

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 reStructuredText 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.
