mainlining shenanigans
6a0678a79b
The inode timestamps use 34 bits in ext4, but the various timestamps in the superblock are limited to 32 bits. If every user accesses these as 'unsigned', then this is good until year 2106, but it seems better to extend this a bit further in the process of removing the deprecated get_seconds() function. This adds another byte for each timestamp in the superblock, making them long enough to store timestamps beyond what is in the inodes, which seems good enough here (in ocfs2, they are already 64-bit wide, which is appropriate for a new layout). I did not modify e2fsprogs, which obviously needs the same change to actually interpret future timestamps correctly.

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.
