[ Upstream commit c473bcdd80d4ab2ae79a7a509a6712818366e32a ]
clang-14 points out that v_size is always smaller than a 64KB
page size if that is configured by the CPU architecture:
fs/nilfs2/ioctl.c:63:19: error: result of comparison of constant 65536 with expression of type '__u16' (aka 'unsigned short') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (argv->v_size > PAGE_SIZE)
~~~~~~~~~~~~ ^ ~~~~~~~~~
This is ok, so just shut up that warning with a cast.

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.
