The following patch disables loading of f2fs module on architectures
which have PAGE_SIZE > 4096 , since it is impossible to mount f2fs on
such architectures , log messages are:
mount: /mnt: wrong fs type, bad option, bad superblock on
/dev/vdiskb1, missing codepage or helper program, or other error.
/dev/vdiskb1: F2FS filesystem,

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
