get_seconds() is deprecated in favor of ktime_get_real_seconds(), which returns a 64-bit timestamp. In the SYSV file system, the superblock timestamp is only 32 bits wide, and it is used to check whether a file system is clean, so the best solution seems to be to force a wraparound and explicitly convert it to an unsigned 32-bit value. This is independent of the inode timestamps that are also 32-bit wide on disk and that come from current_time().

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.
